I have a combined setup with Asterisk-CUBE-CME. The call setup takes place, but as soon the call is picked up by the CME hardphone the call is disconnected.
SIP softphone 1000 -> Asterisk PBX -> CUBE -> CME -> SCCP hardphone 565
The CUBE and CME are part of the same private network. The Asterisk PBX is connected via the internet. All devices and dailpeers are setup with g711ulaw only.
I have a large debug log file with to much information. Can someone advise/help?
