Suppression Of Dtmf Forwarding; System Flag Settings - Polycom RealPresence 1800 Administration Manual

Notes:
• On the Codian gateway Content is not supported with line rates of 128Kbps and below.
• To send 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.
Select Settings > Advanced Commands.
In the Command box, enter H239OlcPatch.
In the Parameters box, enter Enable and click Send.

Suppression of DTMF Forwarding

Forwarding of the DTMF codes from one conference to another over an ISDN-video 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 the 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) in
which MCU A forwards DTMF inputs from conference A participants to MCU B. During that time, the
forwarding MCU does not apply the DTMF command to itself.
Once the timer expires, most of the DTMF codes (excluding five operations as for IP links) entered in
conference A are not be forwarded to conference B, and are applied within the MCU receiving the DTMF
code. 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.
