[OpenSIPS-Users] Memory free problem

[Bogdan-Andrei Iancu]

Hi Denis,

Yes, I see you use Topo Hiding, and as the PRACK is after the 200 OK + 
ACK, OpenSIPS dialog module does not match the PRACK -> it sticks to the 
OpenSIPS IP and loops on it.

If I send you a small patch (to allow PRACK inside dialog) could you 
test it ?
