Hi All

I have a few lines like this at asterisk/messages.

[May 25 15:22:42] WARNING[27725] chan_sip.c: Hanging up call
5a2600300339934f704528bb14ed05e9@MyAsterisk:5060 – no reply to our critical packet (see https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions).

Since we have hundreds of clients with hundreds of simultaneous calls, how is it possible to know to which customer/IP those calls refer to?

The above literature don’t say much to help to narrow down the problem scope.

Cheers

Ethy

  • The string “5a2600300339934f704528bb14ed05e9@MyAsterisk:5060” is the unique identifier for the call in SIP known as the Call-ID. If you have a packet capture of the port 5060 SIP traffic, that identifier will be in each SIP
    message related to the call, which also includes the full from and to details.

    As an alternative to running a separate packet capture, you can enable SIP
    message logging in Asterisk, which puts the full SIP message into the same log file. Be aware however that this can fill your hard drive quite rapidly, as well as put additional load on the disk storage system.

  • That is the problem. Since the message occurs typically about 2~3 times a day (or even less), I will have tons of packets to sniff.

    But, I will give it a try.

    You mean “sip set debug on” ?

    I am pretty aware of that. Learn it the hard way.

    Cheers

  • ​Yes, that’s correct for chan_sip. Sorry, I was vague — there is now a different command for chan_pjsip​, didn’t know which you were using.
