Streammanager/T-Server 7.6 on Cisco CUCM

Hello,

I have done all the configuration for using Streammanager with T-Server Cisco. That was working without problem.
Since the security has installed a firewall between CUCM and Genesys, my annoucement are playing but I do not hear anything (silence only).
Does anyone knows where the stream goes and which port have to be opened in the firewall between Genesys and CUCM ?

Thanks

Hello,

Yes, I know :slight_smile: The call flow is:

1/ Request to play a treatment is issue by URS (routing strategy)
2/ TServer accepts this request and sends request to Stream Manager
3/ Stream Manager replies with port voice path should be connected to
4/ TServer sends request to redirect voice path to specified IP address and port (SM)
5/ CUCM passes information about IP address and port to voice gateway
6/ Once voice gateway establishes the connection Stream Manager starts sending RTP stream

You can define what ports on Stream Manager side will be used for RTP connections. There are 2 options:

  • rtp-port - initial port for RTP/RTCP connection (default value: 8000)
  • max-ports - maximum number of ports for RTP/RTPC connection (default value: 2000)

So by default your firewall should allow communication from voice gateway to SM for ports 8000 - 10000.
