Calls going from a CUCM registered phone through SIP trunk to an SBC continues till there is silence after some 30-40 mins of conversation. On checking the traces, CUCM is sending the message to phone with the invalid IP address of 0.0.0.0.
11/16/2011 20:52:57.668 CCM|StationD: (0046666) OpenReceiveChannel passThruPartyID=84298369 millisecondPacketSize=20 compressionType=4(Media_Payload_G711Ulaw64k) RFC2833PayloadType=0 qualifierIn=? sourceIpAddr=IpAddr.type:0 ipAddr:0x00000000000000000000000000000000(0.0.0.0). myIP: IpAddr.type:0 ipv4Addr:0x0a06776a(10.6.119.106)
What might be the cause for this message ? This is the issue with the remote end or in the CUCM ?
Thanks in advance.
