[cisco-voip] Inbound SIP Calls routing over QSIG link

[ROZA, Ariel]

Nick,

 

A Resources Unavailable message sounds like you need to enable the use
of transcoding for the call.

Hi All

 

I'm trying to route inbound calls from SIP trunks through CUCM to
another PBX connected with QSIG, I have CUCM 8.0.3, with QSIG links to a
IPC dealerboard system and also a Nortel CS1000 PBX, these are set up as
MGCP in CUCM.

 

I also have SIP trunks for PSTN providing both inbound and outbound
calling. The issue I have is when I route inbound calls from the SIP
trunks to CUCM and across the QSIG links to the PBX's, the call will not
complete and I get Resources Unavailable, Unspecified on the debug on
the gateway, I have also taken a SIP trace and get a 503 Service
Unavailable from CUCM to the SIP trunks for the same call.

 

Has anyone successfully done this before and can I route SIP to Qsig or
would I need a CUBE even though its going through CUCM.

 

I have attached the debug and SIP trace.

 

Any help would be greatly appreciated as this is rather urgent now.

 

Regards

 

Nick
