Table 5-24 Configuring the IP-related call settings

Field Name Description

DTMF RFC2833 (H.323) DTMF describes a method to send DTMF inside an

audio stream. This method is normally used in SIP

protocol but is uncommon in H.323.

If set to Yes, the H.323 application in the XT Codec

Unit can use DTMF transmission. Verify the remote

endpoint supports RFC2833 before enabling this

field.

RTP Firewall If set to Yes, the XT Codec Unit checks the audio

and video packets it receives and rejects those

which are incoherent for the current call.

Select dialing number format mode If your XT Codec Unit is not registered with an

H.323 gatekeeper, you can still place a call to an

endpoint registered with a gatekeeper. Check

which format of dialing the gatekeeper accepts and

configure it in this field: <gatekeeper

number><separator> <extension of the called

endpoint>, or <extension> <separator><number>.

The default syntax is

<number><separator><extension>.

Separator Select the field separator accepted by the

gatekeeper. The default separator is ##.

Step 9

In the web interface, select Save.

Note

In the endpoint, your changes are saved automatically.

Configuring Audio Compatibility with Older Systems

Some older endpoint may be not fully compliant with more recent standard, and thus not able

to recognize and manage recent audio protocols such as Audio G.719 (full band). As a

consequence the audio on these endpoints may not work.

The endpoint administrator should disable specific audio codec if any compliance issue with

older endpoints arises.

Procedure

Step 1

Access the audio settings as follows:

•

From the web interface, select Administrator Settings > Calls > Preferences > Audio.

•

From the endpoint, select Configure > Advanced > Calls > Preferences > Audio.
