CUCM => (SIP) => CUBE => ISDN(E1) (PSTN)
Inbound calls suddenly stopped work. Router receives the call on POTS dial-peer , sends to CUCM via SIP. Once the router receives Trying and Ringing from CUCM , it immediately sends Cancel to CUCM with Reason: Q.850;cause=47.
Would appreciate your help,
Thanks in advance
please share the calling number, called number and timestamp to look into debugs.
@ilyas.safarov have looked at the logs you uploaded.
between CUCM and Voice Router you have SIP trunk.
Before the CANCEL event, below is the error being reported.
Sending CANCEL to the transport layer
Jul 7 08:46:54.675: //1648807/3E46959A8127/SIP/Transport/sipSPITransportSendMessage: msg=0x66B8C2C0, addr=192.168.3.10, port=5060, sentBy_port=0, local_addr=, is_req=1, transport=1, switch=0, callBack=0x347EA070
Make sure your SIP trunk between Voice Router and CUCM is UP. I suspect voice router is unable to communicate with CUCM 192.168.3.10, port=5060.
