This guide describes basic use of the Sipura Technology SPA phone adapter – an intelligent lowdensity Voice over IP (VoIP) gateway. The SPA e nables carrier class residentia l and business IP
Telephony services de livered over broadband or high-speed Internet connect ions. By intelligent, we
mean the SPA maintains the states of all the calls it terminates. It is capable of making proper
decisions in reaction to user input events (such as on/off hook or hook flash) with little or no
involvement by a ‘middle-man’ server or media gateway controller.
Examples of proper reactions are: playing dial tone, collecting DTMF digits, comparing them against a
dial plan and term inating a call. With inte lligent endpoints at the e dges of a network , performing the
bulk of the call pr ocessing duties, the dep loyment of a large networ k with thousands of subsc ribers
can scale quickl y without the introduction of complic ated, expensive servers. As desc ribed later in
this section, the S ession Initiation Protocol ( SIP) is a good choice of call s ignaling protocol for the
implementation of such a device in this type of network.
1.1. SPA Hardware Overview
The SPA has one of the smalles t f orm f actor s on the mar k et. It can be ins tall ed in minutes as a tabletop or wall mount CPE device. The images belo w show the SPA-2000. The SPA- 1000 and SPA3000 are similar to size and shape – the only difference being the color of the adapter.
Figures Figure 1, Figur e 2, Figure 3 and Fi gure 4 show the front, re ar, left side and right s ide of the
SPA-2000, respectively.
The SPA has the following interfaces for networking, power and visual status indication:
1. Two (2) RJ-11 Type Analog Telephone Jack Interfaces (Figure 4, above):
These interfaces ac cept standard RJ-11 telephone c onnectors. An Analog touc htone telephone or
fax machine m ay be conne cted to either int erf ace. If the s ervic e sup ports o nl y one incoming line, the
analog telephone or f ax machine sho uld be connec ted to port one ( 1) of the SPA. Port one (1) is the
outermost telephone port on the SPA and is labeled “Phone 1.”
The SPA-3000 has an RJ-11 interfac e labeled “Line” which can be used to connect the adapter to a
PSTN analog telephone circuit.
2. One LED for Unit Status (Figure 4, above):
3. One Ethernet 10baseT RJ-45 Jack Interface (
Figure 2, above):
This interface acc epts a standard or crossover Ethernet cable with s tandard RJ-45 connector. For
optimum perf ormanc e, Si p ura Technology recommends that a Category 5 cable or greater b e used in
conjunction with the SPA.
4. One LED for Data Link and Activity (
Figure 2, above):
5. One 5 Volt Power Adapter Interface (
Figure 2, above)
This interface acc epts the SPA power adapter that c ame with the unit. Sipura T echnology does not
support the use of any other power adapters other then the power a dapter that was s hipped with the
SPA unit.

Note: Do not conn ect RJ-11 telephone cable from the SPA-1000 or SPA-2000 to th e wall jack to
prevent any chance of connec tion to the circuit switched telco ne twork.You may now insert the plu g
end of the power adapter into a live power outlet which will power up the SPA.
3.1.1.1. Firmware Upgrade
Firmware Upgrade via PC Utility Program:
From time to time, Sipura Technology will make available a PC executable file that will facilitate the
upgrade of a SPA. In order to upgrade a device via this method, the end user must have
administrative permission (via password protected log-in) to perform this upgrade.
Once the user has obtained the proper firmware upgrade executable, the user simply runs the
program from a file location on their local PC. The PC program walks the user through the upgrade
process via a graphical user interface. Generally, the entire upgrade process should take no more
than five minutes to complete.
Please note: Some end-users who have obtained their SPA directly from a service provider will never
need to manually upgrade their device. Via the remote upgrade process, Sipura Technology provides
capability for the SPA to be maintained from a remote location (e.g. a service provider network
server), using the Internet connection of the end-user as the conduit through which profile updates
and firmware upgrades are performed.
3.2. IVR Interface
Administrators and/or users can chec k (read) and set ( write) basic net work configuration s ettings via
a touchtone telephone connected to one of the RJ-11 phone ports of the SPA.
Please Note:
Service Providers of fering service using the SPA may restrict, protect or turn of f certain aspects of the
unit’s IVR and web configuration capabilities.
The Interactive Voice Res ponse (IVR) capabi lities of the SPA are des igned to give the adminis trator
and/or user basic rea d/write capabilities such that the unit c an attain basic IP network connectivit y
and the more advanced browser-based configuration menu may be accessed.
1. The SPA IVR uses the following conventions: By factory default there is no password and no
password authentication is prompted for all the IVR settings. If administrator password is set,
password authentic ation will be prompted f or certain I VR settings . See 3.4.2 f or detailed inform ation
about administrator password.
To input the password using the phone keypad, the following translation convention applies:
o To input: A, B, C, a, b, c -- press ‘2’
o To input: D, E, F, d, e, f -- press ‘3’
o To input: G, H, I, g, h, i -- press ‘4’
o To input: J, K, L, j, k, l -- press ‘5’
o To input: M, N, O, m, n, o -- press ‘6’
o To input: P, Q, R, S, p, q, r, s -- press ‘7’
o To input: T, U, V, t, u, v -- press ‘8’
o To input: W, X, Y, Z, w, x, y, z -- press ‘9’
o To input all other characters in the administrator password, press ‘0’
Note: This translation convention only applies to the password input.
For example: to input password “test#@1234” by phone keypad, you need to press the following
sequence of digits: 8378001234.
2. After entering a value, press the # (pound) key to indicate end of input.
o To Save value, press ‘1’
o To Review the value, press ‘2’
o To Re-enter the value, press ‘3’
o To Cancel the value entry and return to the main configuration menu, press ‘
Notes:
o The final ‘#’ key won’t be counted into value.
o Saved settings will take effect when the telephone is hung-up and if necessary, the S PA will
automatically reboot.
3. After one minute of inactivity, the un it times out. T he user will need to re-en ter the configurat ion
menu from the beginning by pressing * * * *.
4. If, while entering a valu e (lik e an IP addr ess) and you d ecid e to exit with out enter ing an y changes ,
you may do so by pressing the * (star) key twice within a half second window of tim e. Otherwise,
the entry of the * (star) key will be treated as a dot (decimal point).
Example: To enter IP addres s, use numbers 0 – 9 on the telephone ke y pad and use the * (star) key
to enter a decimal point.
To enter the following IP address value: 192.168.2.215
A. Use the touchtone key pad to enter: 192*168*2*215#
B. When prompted, enter 1 to save setting to configuration.
C. Hang-up the phone to cause setting to take effect.

3.3. Web Interface
The SPA provides a built-in web server. C onfigurati on and adm inistration c an be perfor med through
this convenient web interf ac e.
3.3.1. Web Interface Conventions
The SPA uses the following conventions with the web administration capabilities:
o The SPA web adm inistration supports two privil ege levels: Administrator and U ser. To use
the User privilege, simply point a web browser at the IP address of the SPA; to use the
administrator privilege, use URL http://IP_Address_Of_SPA/admin
information about administration privileges.
o Version 1.0 of the SPA supports Internet Explorer 5.5 and above and Netscape 7.0 and
above.
o The web configuration pages can be password protected. See 3.3.2 for more information
about password protect.
o The user name of web Administrator is : admin
o The user name of web User is : user
o Note: The user names for both administrator and User are fixed and cannot be changed.
o After making changes to SPA configuration parameters, pressing “Submit All Changes”
button will apply all th e changes and if necessar y, automatically reboot the devi ce. Multiple
changes may be made on multiple page tabs of the web int erf ac e at the s ame time. Pressing
“Submit All Changes” will apply all the modifications.
Important Note: switching between page tabs won’t apply the changes to SPA, The only way
to apply the changes is to press the “Submit All Changes” button.
o If the “Undo All Changes” button is clicked, an y modifications to prof ile parameters on any and
all pages will be reset back to their original values before modification.
NOTE: Pressing the “Undo All Changes” has no effect on the SPA; it will only reset the
values on the web page.
3.3.2. Administration Privileges
The SPA supports t wo levels of adm inistration pr ivileg es: Adm inistrator a nd User, both pr ivileges can
be password protecte d. Im portant note: b y factory default, there ar e n o pass words assigned for b oth
Administrator and User.
The Administrator h as the privil ege to modif y all the web prof ile parameters and can also m odify the
passwords of both Administrator and User. A User only has the pr ivilege to access part of the web
profile parameter s ; the par ameter group that User c an ac ces s is s pec if ie d by the Administrator , which
can only be done through provisioning.
To access the Administrator level privilege, use URL: http://IP_Address_Of_SPA/admin
/. If the
password has been set f or Administrator, the browser will prom pt for authentication. The username
for Administrator is “admin” and cannot be changed.
To access the User lev el privilege, use URL: http://IP_Address_Of_SPA/
. If the password has be en
set for User, the br owser will prompt for User auth entication. The username f or User is “user” and
cannot be changed.
When browsing Adm inistrator pag es, one can s witch to User pri vileges b y click the link “User Login”.
(Note: if User password was set, the br owser wil l prompt for User authenticatio n when you clic k “User
Login” link). On the other side, from the User pages you can switch to Administrator privilege by
clicking the link “Admin Login.” Authentication is needed if Administrator password has been set.
Warning: S witching between the User and Administrator will discard the uncom mitted changes that
have already been made on the web pages.
3.3.3. Basic and Advanced Views
The web configuration interface provides a Basic and an Advanced view from which the various
configuration parameters can be accessed. The SPA Provisioning tab is only visible from the
Advanced Administr ator vie w of the web interf ace.
Warning: Switching between the bas ic and a dv anc ed vie w will d isc ar d the u ncommitted changes that
have already been made on the web pages.
3.3.3.1. Resync URL
Through Resync URL you can force the SPA to do a resync to a profile specified in the URL.
Note: The SPA will resync only when it is idle.
The syntax of Resync URL is:
If no parameter follows “/resync?”, the profile rule setting in provisioning is used. See Error! Reference source not found. for detailed information about profile rule in provisioning
If no protocol is specif ied, TFTP protocol is assumed. Note: O nly TFTP is supported in the current
release.
If no server-name is specified, the host that requests the URL is used as server-name.
If no port specified, default port of the protocol is used – 69 for TFTP.
The profile-path is the path to the new profile to resync with.
For example: http://192.168.2.217/upgrade?tftp://192.168.2.251/spaconf.scf
3.3.3.2. Reboot URL
Through the Reboot URL, you can reboot the SPA.
Note: Upon request, the SPA will reboot only when it is idle.
The Reboot URL is: http://<spa-ip-addr>/admin/reboot

Range: 0 – 255 (s)
Notes:
1. Reorder or Busy Tone will be played by default for all unsuccessful response status code
2. <RTP Port Min> and <RTP Port Max> should define a range that contains at least 4 even number
ports, such as 100 – 106
3. If inbound SIP requests contain compact headers, SPA will reuse the same compact headers
when generating th e respons e regardless the set tings of the <Use Compact Hea der> param eter.
If inbound SIP requests contain norm al headers, SPA will substitute th ose headers with compact
headers (if defined by RFC 261) if <Use Compact Header> parameter is set to “yes.”
4. During an active connec tion, the SPA can be pr ogrammed to send out compound RTCP p acket
on the connection. Each compound RTP packet except the last one contains a SR (Sender
Report) and a SDES.(Source Description). The last RTCP packet contains an additional BYE
packet. Each SR ex cept the last one conta ins exac t l y 1 RR (R ec ei ver Report); the last S R car r ies
no RR. The SDES cont ains CNAME, NAME, and TOOL ident ifiers. The CNAME is set to <User
ID>@<Proxy>, NAME is set to <Display Name> ( or “Anonymous” if user block s caller ID), and
TOOL is set to the Verdor/Hardware-platform-software-version (such as Sipura/SPA2000-
1.0.31(b)). The NT P timestam p used in the SR is a snaps hot of the S PA’s loc al ti m e, not the tim e
reported by an NTP server. If the SPA rec eives a RR f rom the peer, it will a ttem pt to com pute the
round trip delay and show it as t he <Cal l Ro un d T r ip Dela y> value (ms) in the Info section of SPA
web page.
2. The configured d ynamic payloads are used for outbou nd calls only where the SPA prese nts the
SDP offer. For inbound calls with a SDP offer, SPA will follow the caller’s dynamic payload type
assignments
3.4.4.2. SDP Audio Codec Names

Proxy or Outbound Proxy name with _sip._udp
when performing a DNS SRV lookup on that name
Proxy Fallback Intvl This parameter sets the delay (sec) after which the
3600
SPA will retry from the highest priority proxy (or
outbound proxy) servers after it has failed over to a
lower priority server. This parameter is useful only if
the primary and backup proxy server list is provided
to the SPA via DNS SRV record lookup on the
server name. (Using multiple DNS A record per
server name does not allow the notion of priority
and so all hosts will be considered at the same
priority and the SPA will not attempt to fall back
after a fail over)
Display Name Subscriber’s display name to appear in caller-id
User ID Subscriber’s user-id. Usually a E.164 number
Password Subscriber’s a/c password
Auth ID Subscriber’s authentication ID
Use Auth ID If set to “yes”, the pair <Auth ID> and <Password>
No
are used for SIP authentication. Else the pair <User
ID> and <Password> are used.
Mini Certificate Base64 encoded of Mini-Certificate concatenated
Empty
with the 1024-bit public key of the CA signing the
MC of all subscribers in the group.
SRTP Private Key Base64 encoded of the 512-bit private key per
Empty
subscriber for establishment of a secure call.
Notes:
1. If proxy responded to REGISTER with a smaller Expires valu e, the SPA will renew registration
based on this sm aller value inste ad of the configured value. If regist ration failed with an “Expires too
brief” error respons e, the SPA will retry with the value given in the M in-Expires header in the error
response.
2. MOH Notes:
• The remote party mus t indic ate t hat it c an r ece iv e au dio whi le h ol din g MO H t o work. That is the SIP
2xx response from the remote party in reply to the re-INVITE fr om the SPA to put the call on hold
must have the SDP i ndicate a sendrec v or recvo nly attribut e and the r emote des tinatio n address and
port must not be 0
3. SAS Notes:
• Either or both of lines 1 and 2 can be configured as an SAS server.
• Each server can maintain up to 5 simultaneous calls. If the second line on the SPA is disabled, then
the SAS line can maintain up to 10 simultaneous calls. Further incoming calls will receive a busy
signal (SIP 486 Response).
• The streaming audi o source m ust be off-hook for the stream ing to occur. Othe rwise incom ing calls
will get a error response (SIP 503 Response). The SAS line will not ring for incoming calls even if the
attached equipment is on-hook
• If no calls are in sess ion, batter y is removed from tip-and-ring of the FXS port. Some audio so urce
devices have an L ED to indicate the b attery status. T his can be used as a visual indication whether
any audio streaming is in progress.
• IVR can still be used on an SAS line, but th e user needs to f ollo w som e simple s teps: a) Connect a
phone to the port and make sur e the phone is on-hook , b) power on the SPA and c ) pick up handset
and press * * * * to invoke IVR in the usual way. The idea behin d this is that if th e SPA boots up and
finds that the SAS line is on-hook, it will not r emove battery from the line so that IVR ma y be used.
But if the SPA boots up and f inds that the SAS line is off-hook, it will remove batter y from the line
since no audio session is in progress.
• Set up the Proxy and Su bscr iber Inf orm ation for the SAS Li ne as you norm all y would with a re gular
user account.
• Call Forwarding, Call Screening, Call Blocking, DND, and Caller-ID Delivery features are not
available on an SAS line.
The SPA provides nati ve support of a large s et of enhanced or suppl ementary services. Al l of these
services are optional. The parameters listed in the following table are used to enable or disable a
specific supplem entary service. A supplementar y service should be disabled if a) the user has not
subscribed for it, or b) the Ser vice Pro vider inten ds to support s imilar s ervice using oth er means than
relying on the SPA.

Preferred Codec Select a preferred codec for all calls. However, the
G711u
actual codec used in a call still depends on the
outcome of the codec negotiation protocol.G711u,
G711a, G726-16, G726-24, G726-32, G726-40,
G729a, G723

None
• None: do not signal hook flash events
• AVT: use RFC2833 AVT (event=16)
• INFO: use SIP INFO method with the single line
“signal = hf” in the message body. The MIME type for
this message body is taken from the <Hook Flash
MIME Type> paramter
Release Unused Codec Yes
Notes:
1. A codec resource is co nsidered as allocated if it has been included in the SDP codec lis t of an
active call, even though it even tuall y ma y not be the one chos en for the connec tion. So, if the G.72 9a
codec is enabled and included in the codec list, that resource is tied up until the end of the call
whether or not the call ac tually uses G.729a. If the G729a res ource is already allocated and si nce
only one G.729a resource is allowed per SPA, no other low-bit-rate codec may be allocated for
subsequent calls; the only choices are G711a and G711u. On the other hand, two G.723.1/G.726
resources are availab le per SPA. Therefore it is im portant to disable the use of G.729a in ord er to
guarantee the support of 2 simultaneous G.723/G.726 codec.
3.4.5.4. Dial Plan
See section 6 for additional information regarding the configuration of the SPA dial plan.
Parameter Name Description Default
Dial Plan Per-line dial plan script See below
Enable IP Dialing Enable IP Dialing no
See the previous section for explanation of Dial Plan Script syntax.
Default Dial Plan script for each line:
“(*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxx|xxxxxxxxxxxx.)”
Explanation of Default Dial Plan:
Dial Plan Entry Functionality
*xx Allow arbitrary 2 digit star code
[3469]11 Allow x11 sequences
0 Operator
00 Int’l Operator
[2-9]xxxxxx US "local" number
1xxx[2-9]xxxxxx US 1 + 10-digit long distance number
xxxxxxxxxxxx. Everything else (Int’l long distance, FWD, ...)
Note: If IP dialing is enabled, one c an dial [user -id@]a.b.c .d[:port], wh ere ‘@’, ‘.’, and ‘:’ are di aled b y
entering “*”, user-id m ust be numeric (like a phone n umber) and a, b, c, d must be bet ween 0 and
255, and port must be larger than 255. If port is not given, 5060 is used. Port and User-Id are
optional. If the user-id portion matches a pattern in the d ial plan, then it is interpreted as a r egular
phone number according to the dial p lan. T he INVIT E m essage, howe ver, is still s ent to th e outbou nd
proxy if it is enabled.
