What is DGW-L1
OpenVox T1/E1 Gateway is an open source asterisk-based VoIP Gateway solution for operators and call centers. It is a converged media
gateway product. This kind of gateway connects traditional telephone system to IP networks and integrates VoIP PBX with the PSTN seamlessly.
With friendly GUI, users may easily setup their customized Gateway. Also secondary development can be completed through AMI (Asterisk
Management Interface). The DGW-L1 could support 12v power supply.
It is developed with a wide selection of codecs and signaling protocol, including G.711A, G.711U, G.729, G.722, G.723 and GSM. It supports
PRI/SS7/R2 protocol. OpenVox T1/E1 Gateway has good processing ability and stability. The T1/E1 gateway will be 100% compatible with
Asterisk, Elastix, trixbox, 3CX, FreeSWITCH SIP server and VOS VoIP operating platform.

You can click button to add a new SIP endpoint, and if you want to modify existed endpoints, you can click button.
There are 3 kinds of registration types for choose. You can choose Anonymous, Endpoint registers with this gateway or This gateway registers
with the endpoint.
You can configure as follows:
If you set up a SIP endpoint by registration “None” to a server, then you can’t register other SIP endpoints to this server. (If you add other SIP
endpoints, this will cause Out-band Routes and Trunks confused.)
Figure 4-1-2 None Registration
For convenience, we have designed a method that you can register your SIP endpoint to your gateway, thus your gateway just work as a server.
Figure 4-1-3 Endpoint Register with Gateway
Also you can choose registration by “This gateway registers with the endpoint”, it’s the same with “None”, except name and password.

Hostname
or IP
Address
IP address or hostname of the endpoint or 'dynamic' if the endpoint has a dynamic IP address. This will require registration.
Notice: if the input here is hostname and your DNS has changed, you must reboot asterisk.
Transport This sets the possible transport types for outgoing. Order of usage, when the respective transport protocols are enabled, is UDP,
TCP, TLS. The first enabled transport type is only used for outbound messages until a Registration takes place. During the peer
Registration the transport type may change to another supported type if the peer requests so.

In some cases,T.38 endpoints will provide a T38FaxMxDatagram value (during T.38 setup) that is based on an incorrect
interpretation of the T.38 recommendation, and result in failures because Asterisk does not believe it can send T.38 packets of a
reasonable size to that endpoint (Cisco media gateway are one example of this situation).In these cases, during a T.38 call you
will see warring messages on The console/in the logs from the Asterisk UDPTL stack complaining about lack of buffer space to
send T.38FaxMaxDatagram value specified by the other end[point, and use a configured value instead.

Subscribe
Network Change
Event
Through the use of the test_stun_monitor module, the gateway has the ability to detect when the perceived external network
address has changed. When the stun_ monitor is installed and configured, chan_sip will renew all outbound registrations
when the monitor detects any sort of network change has occurred. By default this option is enabled, but only takes effect
once res_stun_monitor is configured. If res_stun_monitor is enabled and you wish to not generate all outbound registrations
on a network change, use the option below to disable this feature.
Match External
Address Locally
Only substitute the exeternaddr or externhost setting if it matches
Dynamic
Exclude Static
Disallow all dynamic hosts from registering as any IP address used for staticly defined hosts .This helps avoid the
configuration error of allowing your users to register at the same address as a SIP provide.

Mapped TCP
Port
The externally mapped TCP port, when the gateway is behind a static NAT or PAI
External
Address
The external address (and optional TCP port) of the NAT. External address=hostname [:port] specifies a static
address[:port] to be used in SIP and SDP messages. Examples: External address=12.34.56.78 External
address=12.34.56.78.9900

Hostname
The external hostname (and optional TCP port) of the NAT.
External Hostname=hostname[:port] is similar to
“External address”. Examples:

Disallowed SIP
Methods
When a dialog is started with another SIP endpoint, the other endpoint should include an Allow header telling us what SIP
methods the endpoint implements. However, some endpoint either do not include an Allow header or lie about what
methods they implement. In the former case, the gateway makes the assumption that the endpoint support all known SIP
methods. If you know that your SIP endpoint does not provide support for a specific method, then you may provide a list of
methods that your endpoint does not implement in the disallowed_ methods option. Note that if your endpoint is truthful
with its Allow header, then there is need to set this option.
Shrink Caller ID The shrinkcallerid function removes '(', ' ', ')', non-trailing '.', and '-' not in square brackets. For example, the caller id value
555.5555 becomes 5555555 when this option is enabled. Disabling this option results in no modification of the caller id
value, which is necessary when the caller id represents something that must be preserved. By default this option is on.

Realm for digest authentication. Realms MUST be globally unique according to RFC 3261. Set this to your host name or domain
name.
Use
Domain
as Realm
Use the domain from the SIP Domains setting as the realm. In this case, the realm will be based on the request 'to' or 'from'
header and should match one of the domain. Otherwise, the configured 'realm' value will be used.
Always
Auth
Reject
When an incoming INVITE or REGISTER is to be rejected, for any reason, always reject with an identical response equivalent
to valid username and invalid password/hash instead of letting the requester know whether there was a matching user or peer
for their request. This reduces the ability of an attacker to scan for valid SIP usernames. This option is set to 'yes' by default.

Requests
Enabling this option will authenticate OPTIONS requests just like INVITE requests are. By default this option is disabled.
Allow Guest

Allow or reject guest calls (default is yes, to allow). If your gateway is connected to the Internet and you allow guest calls, you
want to check which services you offer everyone out there, by enabling them in the default context.

Table 4-3-4 Instruction of Jitter Buffer
Options Definition
Jitter Buffer Global default as to whether you want the jitter buffer at all
Force Jitter Buffer In the ideal world, when we bridge VoIP channels we don’t want to jitter buffering on the switch, since the endpoints can each handle this.
However, some endpoints may have poor jitter buffers themselves, so this option will force to always jitter buffer, even in this case.
Max Jitter Buffers A maximum size for the jitter buffer
Resyncthreshold When the jitter buffer notice a significant change in delay that continue over a few frames, it will resync, assuming that the change in delay
was caused by a timestamping mix-up. The threshold for noticing a change in delay is measured as twice the measured jitter plus this
resync threshold.
Max Jitter Interps The maximum number of interpolation frames the jitter buffer should return in a row. Since some clients do not send CNG/DTX frames to
indicate silence, the jitter buffer will assume silence has begun after returning this many interpolations. This prevents interpolating
throughout a long silence.
Jitter Target Extra Number of milliseconds by which the new jitter buffer will pad its size. The default is 40, so without modification, the new jitter buffer will set
its size to the jitter value may help if your network normally has low jitter, but occasionally has spikes.

rules.
Call Routing Rule
There is an example for Routing rules number conversion, it transform calling, called number at the same time. Suppose you want eleven
numbers start at 159 to call the eleven numbers of start at 136. Calling transform delete the three numbers from left, then writing number 086 as
prefix, delete the last four numbers, and then add number 0755 at the end, it will show caller name is OpenVox. Called transform adds 086 as
prefix , and Change the last two number to 88.

You can click button to set up your routings.
Figure 5-1-3 Example of Set Up Routing Rule
The figure above realizes that calls from “support” SIP endpoint switch you have registered will be transferred to Port-1. When “Call Comes in
From” is 9000, “prepend”, “prefix” and “match pattern” in “Advanced Routing Rule” are ineffective, and just “CallerID” option is available.

Dial Patterns
that will use
this Route
A Dial Pattern is a unique set of digits that will select this route and send the call to the designated trunks. If a dialed pattern
matches this route, no subsequent routes will be tried. If Time Groups are enabled, subsequent routes will be checked for
matches outside of the designated time(s).
Rules:
matches any digit from 0-9X
matches any digit from 1-9Z
matches any digit from 2-9N
[1237-9] matches any digit in the brackets (example: 1,2,3,7,8,9)
. matches one or more dialed digits: matches one or more dialed digits.
: Digits to prepend to a successful match. prepend
If the dialed number matches the patterns specified by the subsequent columns, then this will be prepended before sending to
the trunks.
prefix: Prefix to remove on a successful match.
The dialed number is compared to this and the subsequent columns for a match.
Upon a match, this prefix is removed from the dialed number before sending it to the trunks.
match pattern: The dialed number will be compared against the prefix + this match pattern.
Upon a match, the match pattern portion of the dialed number will be sent to the trunks
SDfR(Stripped Digits from Right): The amount of digits to be deleted from the right end of the number. If the value of this item
exceeds the length of the current number, the whole number will be deleted.
RDfR( Reserved Digits from Right) :Designated information to be added to the right end of the current number.
StA(Suffix to Add):Designated information to be added to the right end of the current number.
Caller Name: What caller name would you like to set before sending this call to the endpoint. Native language charset is
allowable, e.g. Chinese charset, Latin charset.
Forward
Number
What destination number will you dial?
This is very useful when you have a transfer call.
Failover Call
Through
Number
The gateway will attempt to send the call out each of these in the order you specify.
You can create various time routes and use these time conditions to limit some specific calls.
Figure 5-1-4 Advance Routing Rule
Figure 5-1-5 Time Patterns that will use this Route
If you configure like this, then from January to March, from the first day to the last day of these months, from Monday to Thursday, from 00:00 to
02:00, during this time (meet all above time conditions), all calls will follow this route. And the time will synchronize with your Sever time.

You can configure forward number when you have a transfer call.
Figure 5-1-7 Failover Call Through Number
You can add one or more “Failover Call Through Numbers”.
Groups
Sometimes you want to make a call through one port, but you don’t know if it is available, so you have to check which port is free. That would be
troublesome. But with our product, you don’t need to worry about it. You can combine many Ports or SIP to groups. Then if you want to make a
call, it will find available port automatically.
