[OpenSER-Users] Formation of ACKs?

[Tobias Lindgren]

Hi Marcello,

I'm not matching them as you suggest, so that might very well be the case. I'll try it, thanks!

Hi,
are you sure that Openser is processing the ACK packet with t_relay() to 
match it against existing transaction?
This is the same issue i had 2 days ago and solved putting a:

        if (method=="CANCEL" || method=="ACK") {
                route(1);
                return;
       }

in my main routing block. The route[1] is route block that process 
request with t_relay().
Before i didn't put the ACK in the if clause but only the CANCEL.
Hope to helped,
Bye,
Marcello
