Hi
I have the following setup CUCM 6 -- > H323 GW ---- > SIP from same GW ---- > SIP provider
WHen i dial a number across the SIP provider the number rings ,but as soon as i answer the call the call gets dropped ,but from the SIP debugs on the gateway i can not see any reason for it ,the codec negotiation goes through fine ,only error is see is :
May 29 14:59:18: //-1/xxxxxxxxxxxx/SIP/Error/sipSPIUcccause_to_sipcause: Unknown PSTN cause code from CCAPI:0
Spoke to the SIP provider and he reckons he sees a disconnect from my side.
I will attach a copy of the sip debug
Does anyone know what the issue might be here ?
