[Kamailio-Users] [dialog module] dialog is not terminated when no ACK is received

[Iñaki Baz Castillo]

Hi, using Kamailio 1.5.4.

I use dlg_manage() for an INVITE. 200 Ok is replied by the callee but the UAC 
doesn't send the ACK (due to a crash).

The dialog remains in Kamailio dialog memory/table in state 3 and would expire 
after default_timeout (which usually is 3600 seconds or more, unsuitable for 
this case).

Yes, it could occur that the proxy is not doing loose_routing, but in that 
case it doesn't make sense to use dialog module, so shouldn't dialog module 
expire dialogs in state 3 after ~32 seconds?

I'm using profiles_with_value to limit the number of calls per user, so this 
issue is a bit important, as a UAC not sending the ACK for a 200 means one 
less available channel for this user during dialog module default_timeout.
