We have a Cisco Callmanager at our company:
System version: 22.214.171.1240-1
I've tried and succeeded to registed a Nokia N97 to the callmanager using the inbuild SIP protocol and downloaded SIP_VoIP_3_1_Settings_S60_5_x_v1_0_en.sis voip addon.
The phone is successfully registered via our wifi network, I can make calls to other phones, but when I call the N97's DN the phone won't call/ring. And I get an cisco voice message saying my call can't get completed.
When I unregister, and I call the N97, it gives me an out of service tone, wich is normal.
Does anyone know the sollution? Or tell me how to proper debug the failed call I'm trying to make?
