Hello,

this sounds like the ACK is  not matched for dialog processing and the early_timeout is firing. I just pushed a commit to dialog module to print the old state when the timeout callback function is executed, maybe you can test with it -- it is in branch 5.3:

  - https://github.com/kamailio/kamailio/commit/ff2f8c4e63b4fefa7dc5b10835505c3c4ae84388

Otherwise, maybe call dlg_manage() for ACK, although the loose_route() callback should be executed and ACK handled for dialog processing.

Cheers,
Daniel

Hello,

I'm trying to get CDR working in Kamailio by using the acc and dialog modules. Everything seemed to be working fine - until i noticed that for some of the calls the call duration is 0, even if that call has been successfully established and duration was for about a few minutes. In the Kamailio logs I'm getting such errors:

WARNING: dialog [dlg_handlers.c:1649]: dlg_ontimeout(): timeout for dlg with CallID '304bad142b50bb3a7a117816439ea3d5' and tags 'as3adde5c7' '7d28152f-e0e3-4bcf-9d5c-21c3723b95c5'

WARNING: acc [acc_cdr.c:230]: db_write_cdr(): fallback to dlg_only search because of message doesn't exist.

This error I'm getting at about 2 min after the ACK message for 200 OK. I'm not sure that this is related to the dialog timeout, but below you can see the related configuration for the dialog module:

modparam("dialog", "default_timeout", 10800) # 3 hours

modparam("dialog", "early_timeout", 180)

modparam("dialog", "noack_timeout", 90)

Unfortunately, I'm not able to reproduce this issue, as that's happening randomly and just a few times per day. On the SIP Level i didn't notice any strange issues.

Any ideas why is that happening?

Thank you.
