When you intend to have displayed only those user records where the extension number starts
with 5, enter 5 in the field Phone and click . When it is necessary to further narrow
the search and display only user records that have phone numbers starting with 509, enter 509 in
the field Phone and click .
You can perform search by a digit or digits the phone number starts with and cannot search by
digits occurring in the middle or in the end of the number. You cannot enter regular expressions
in the filter field Phone either.
The search argument entered in the field Name is an alphabetic character or several characters
that can be found as a substring occurrence within a name string. The performed exact-match
search is case insensitive. For example, if you enter the letter A in the Name field and click
the search will return all user records where the user name includes characters A
and a, regardless of their number and position within the name string.
The search argument in the filter field Group is one selected from the drop-down list.
While using the filter you can define any single search argument, any combination of two
arguments (phone and name, phone and group, name and group) and all three arguments
simultaneously.

4.2.3 USER NAT-, FAX-RELATED AND SIGNALING-DEP END ENT SETTINGS
If necessary, configure other user endpoint properties that include the parameters shown in Fig.
16:
DVX-7090 VoIP Router page 18 of 83
Configuration
Fig. 16 NAT- , fax-related and protocol-specific settings
The combo box NAT serves to select a NAT traversal policy and offers triple choice:
- direct means that call packets will go direct without enabling NAT traversal
- forced stands for the NAT traversal function enabled
- detect denotes automatic detection of NAT presence
Select direct when you are positive that communication with the endpoint you are
configuring does not involve network address translation (NAT). Select the option forced
when it is known that the endpoint sits behind a NAT router. Select detect when unsure
about the situation with NAT.
FAX T.38 allows you to enable/disable T.38 fax support.
The Convert combo box offers three options:
– none (no codec conversion is performed even if the call originator and terminator
have a common codec capability)
– adaptive (the DVX-7090 Router performs codec conversion when necessary, i.e.
when the calling and called endpoints feature no common codec capabilities)
– forced (the DVX-7090 Router always performs conversion of media even when a
common capability exists)
Note: The use of codec conversion should be judicious as codec conversion is very
demanding in terms of the system computing power and takes toll on voice quality. The option
adaptive is the best choice as with adaptive selected the Router tries to put the call through
without conversion and automatically engages the codec converter when the call is impossible
otherwise. The option forced is for extraordinary cases when two endpoints cannot communicate
otherwise even with a common codec capability.
The Repacketize control allows you to manage repacketization of media streams that may be
necessary to improve the quality of speech and remedy possible silence suppression
incompatibility occurring occasionally in terminal equipment. The options of the Repacketize
drop-down list include:
– none disables repacketization of media streams
– incoming (enables repacketization of ingress media)
– outgoing (enables repacketization of egress media)
– both (enables repacketization of ingress and egress streams)
DVX-7090 VoIP Router page 19 of 83
Configuration
DTMF Options the DTMF Options combo box is used to select a type of DTMF digits payload.
The available options include:
1. RFC2833 for all terminal equipment types
2. INFO V.1 for CISCO SIP terminals
3. INFO V.2 for Nortel SIP terminals
Dealing with H.323 Options:
Tunneling enables/disables encapsulation of H.245 messages
Fast Start enables/disables FastStart
Multiple FastStart. With Multiple FastStart set to ‘true’ the system includes FastStart in every
packet
Ext T.38 compatibility
This parameter is intended to overcome slight incompatibilities that frequently exist in vendorspecific implementations of the H.323 standard. For example, setting Ext T.38 compatibility to
true ensures trouble-free interoperation of Vocaltec endpoints with the DVX-7090 Router.
Start H.245 has three options:
- callproceeding
- connect
- alerting
that help you define which of the above H.225 messages will trigger establishment of the
H.245 control channel
Early Connect – this flag is used to ensure smooth interoperation with endpoints that do not
exchange capabilities (codecs etc.) until the arrival of CONNECT. Select true to provide for an
early CONNECT message.
Dealing with SIP Options:
Ringback Tone is used to configure the RBT capability for the endpoint. If the terminal you are
configuring is capable of generating RBT, select local, otherwise select emulate.
Allow SIP Redirect allows/disallows SIP redirection
Allow noproxy when set to true enables signaling proxy only and direct flow of media streams.
The value false enables full proxy, which involves proxy operation for both signaling and media
packets.
Note: Remember that the setting of the parameter Allow noproxy must be the same for both
the calling and the called endpoint
4.2.4 CALL FORWARD DIALOG
Fig. 17 Call forward configuration form
To configure conditional and unconditional call forwarding:
DVX-7090 VoIP Router page 20 of 83
Configuration
1. Click
2. Select a condition (Busy, No answer, Unreachable, Unconditional) that will cause call
forward using the combo box in the column Fwd Condition
3. If the forward rule being configured applies to a particular calling number only, type the
necessary calling number in the edit box Source. Alternatively, you can write a regular
expression that covers a series of numbers.
Leave the edit box intact if the calling number is of no importance for the call forward
you are configuring.
4. When necessary, you can limit call forward to a particular time period and day or days
of week.
To define a call forwarding period, select the checkbox Time (in the column Activity
Schedule) and specify the period start and end time in the edit boxes From and To
respectively. To specify on what days call forwarding will take place, select the
checkbox Days and select call forward days on the drop-down menu invoked by a click
on the appearing down-arrow button.
5. Type in the forward number in the text box Fwd Number of the form and click
to validate the changes you have made to the record.
4.2.5 CODEC CAPABILITY SETTINGS
The add-new-user dialog appears with all codecs in place and frame-per-packet settings done
(see Fig. 18.) If you wish to delete unnecessary codecs, click the delete button
To add to the codec capability of the user’s terminal, click
required codec from the drop-down list of codec options.

Configuration
Fig. 18 Codeсs options
Enter a number of frames per packet in the neighboring edit box FPP with due regard to the
endpoint capability and buffer size. Information about codec frame sizes is given in the table
below.
Table 2 Frame sizes by codecs
Codec Frame size
G.729 10 ms
G.729A 10 ms
G.723 30 ms
G.711-aLaw 1 ms
G.711-uLaw 1 ms
GSM 06.01 20 ms
Therefore, if an endpoint can accept no more than, say, 60ms worth of audio per packet, for
G.711 you can enter the value 60; for G.723 it will be 2 (60/30 = 2); for G.729 it would be 6
(60/10 = 6).
Note: Please, remember that for G.711 codecs it makes sense to enter “frames per packet”
values in multiples of ten only.
You can increase/decrease codec precedence in the table by clicking up- and down-arrow
buttons.
