CUBE sends SIP Cancel to CUCM

[ilyas.safarov]

Hello ,

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.

Attaching debugs. 

Would appreciate your help,

Thanks in advance

Ilyas

@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.

can you attach below details here please.

- show running config

- show dial-peer voice inout

- show inventory

Suggestion, next time when you enable the traces and share it, share it in single file rather in multiple files.

Issue was resolved after Router restart :))
