Error: CSeq: 101 CANCEL

[cisco]

Hi guys,

I'm with a problem, I can't call to specific number: +55 11 49505070 (From Brazil), but just of a specific locale (My enterprise). However, any other locale I can call to number.

I made several test with the telephone service provider, but they did tests and said that the "outside" is ok.

Below is the beginning of the log with the problem:

A. Telecom,

Cancel is a sip method seen when call signalling is abruptly ended before processing 200 ok method by a user agent.

Over here, can you please share below details so that problem can be diagnosed:

a)- What is the call flow?

b)- Is the phone registered on cucm or cme ?

c)- Has it ever worked in past? if yes, then is there any changes made in network?

d)- Share 'show tech' output from router.

e)- Share output of 'debug ccsip messages' along with 'debug voice ccapi inout'

Regards,

Kunal
