CUCM 8.0 - Calling problem
Answer
4/10/11 7:50 PM
Hi,
 
couple of days ago I started working on CUCM 8.0. I managed to register two IP Phones to my CUCM(Third-party SIP Devices).
When I am calling there is a ring on the device, then after answering the phone call is disconnected.
 
Callee sends back 200OK, but CUCM sends to caller message 503 Service Unavailable Q.850 cause 47 service [Resources unavailable, unspecified]. I found somewhere that it could be caused by codecs by my Region is set by default to g.711 so are my devices.
 
Could you please help? Do you have any ideas what could cause such a problem?
 
Thanks in advance,
 
Adam

I reinstalled CUCM on other hardware and changed Third-Party SIP Devices to Basic and it works!
