[Asterisk-Users] RTP path with Cisco CCM

[Patrick Zwahlen]

Hi,

I have the following config:

[7960] <--skinny--> [Cisco CCM] <--SIP_trunk--> [asterisk] <--SIP-->
[X-lite]

Is there a chance to avoid the RTP stream from passing through the Cisco
CCM ? I would like to have all RTP handled by the *.

This is just a testbed, for a larger project. What I want to achieve, is
actually this:

[Cisco Phone] <--skinny--> [Cisco CCM] <--SIP_trunk--> [asterisk]
<--IAX2_trunk--> [asterisk] <--SIP_trunk--> [Cisco CCM] <--skinny-->
[Cisco Phone]

In that case, I need to handle basic calls between the Cisco phones, and
would like to offload the RTP from the CallManagers. RTP needs to pass
through the asterisk servers and the IAX trunk only.

Here is my sip.conf:
======================================
[general]

port = 5060           ; Port to bind to (SIP is 5060)
bindaddr = 0.0.0.0    ; Address to bind to (all addresses on machine)
disallow=all
allow=ulaw
allow=alaw
context = from-sip-external ; Send unknown SIP callers to this context
callerid = Unknown
