Indeed after the PRACK there is no « 18x » packets.

I looked at the code and this log happens when a PRACK is received, but there was no 183 (or other 1xx) response. Can you check the sip traffic and see what packets are sent around?

Cheers,
Daniel

Hello,

I have this error after enabling the PRACK on PBX side.
Is it normal behavior ?
Should I drop the PRACK frames?

Thanks

Hello,

I got this error when passing a call.

CRITICAL: dialog [dlg_hash.c:955]: log_next_state_dlg(): bogus event 5 in state 1 for dlg 0x7f7a17848bd8 [3582:11978] with clid 'ae27f53121fe6d84c6845dedcf2e2793' and tags 'f68d2151b8411946' ''

Any ideas ?
This is a bug ?

Never seen that error before,
