[cisco-voip] Multicast MoH with SIP Trunk

[Ahmed Elnagar]

Hi all;

 

I have a SIP trunk to a CVP that accept incoming calls from the IPCCE
system after the PSTN caller hears the IVR and selects an option to be
transferred to an agent...when PSTN caller transferred and talk with the
agent for  a while then if the agent needs to be the call on hold the
PSTN caller hear nothing "just dead air" I can see on RTMT that a
Multicast MoH device is invoked with this step, but nothing is streamed
from the router.

 

I am sure that M-Moh is working as when the agent starts a direct call
from his phone through the H323 GW "the same that calls come in and the
same that hosts MMoh" and when the agent puts the customer on hold we
are able to here MoH normally and I can see the same device is invoked
on the RTMT and even on the router I can see that there is a Multicast
MoH stream going out on the loopback interface.

 

Any ideas? Is Multicast MoH is not supported with SIP trunk in my
situation "Unicast is working normally by the way".
