Chapter 5-Cascading Conferences

•On the Codian gateway Content is not supported with line rates of 128Kbps and below.

•When using the following topology:

H.323 endpoint ->Codian Gateway -> ISDN Link -> RMX -> H.323 endpoint, the Codian Gateway is unable to send DTMF and the call is disconnected (VNGFE- 3587).

•Sending Content from a participant over Radvision Gateway to a conference/participant, the GWP20 patch must be installed in the RadVision gateway:

On the Radvision gateway, open the GWP20 User Interface. Click Settings/Advanced Commands. In the Command box enter H239OlcPatch. In the Parameters box enter Enable and then click Send.

Suppression of DTMF Forwarding

Forwarding of the DTMF codes from one conference to another over an ISDN cascading link is not automatically suppressed as with IP cascading link and it can be limited to basic operations while suppressing all other operations by a system flag:

DTMF_FORWARD_ANY_DIGIT_TIMER_SECONDS.

System Flag Settings

The DTMF_FORWARD_ANY_DIGIT_TIMER_SECONDS flag determines the time period (in seconds) that MCU A will forward DTMF inputs from conference A participants to MCU B.

Once the timer expires, most of the DTMF codes (excluding five operations as for IP links) entered in conference A will not be forwarded to conference B. This is done to prevent an operation requested by a participant individually (for example, mute my line) to be applied to all the participants in conference B.

Flag range (in seconds): 0 - 360000

This flag is defined on MCU A (the calling MCU).

If a flag is not listed in the System Flags list it must be added to the system.cfg file before it can be modified. For more details on defining system flags, see "Modifying System Flags” on page 22-1.
