[Freeswitch-users] One way audio to CME

[Peter]

I currently have successful two way calls (signalling and media) in the
following setup


External Linphone -->  Freeswitch  --> Freeswitch SBC  -> Router  ->
Kamailio --> Internal Linphone

However, when I try to call a Cisco handset that is registered to CUCM9 via
CME in the following config:

External Linphone -->  Freeswitch  --> Freeswitch SBC  -> Router  -> CME
->  CUCM9 -->  Cisco handset

The call signalling appears to be working fine and I can successfully
initiate a call from each end, but the only RTP stream that is working is
from the external Linphone client to the Cisco handset.

Note that CME is being used as a CUBE device, so all SIP and RTP goes via
it.

Looking at the RTP debugs on CME I can see the problem is that the "Media
Dest Addr" is getting set to the external side of the FS SBC rather than
the internal IP address.


I tried setting adding:

            <action application="set" data="disable_rtp_auto_adjust="true"
/>

to the dialplan on the SBC, but it made no difference.


Any suggestions as to what to check next?

Thanks

Peter
