Hi *,<br><br>Here is the trace. One thing I have noticed is that the 180 Ringing being returned from the Snom phone (behind the NAT) contains the contact header still with the private IP (192.168.1.100). Theoretically though I don&#39;t see how this can affect the transaction handling - maybe you can shed some light.<br>

Hi *,<br>
<br>
What is the logic behind the transation matching in Kamailio. I am finding a problem whereby a call setup transaction (INVITE, 180 Ringing, PRACK, 200OK, ACK). between 2 Snom phones works in normal mode. However, when one phone is behind a NAT with STUN support, everything works perfectly (i.e. call setup, 2-way audio, etc), BUT the tm module doesnt match the transaction between the original invite and the subsequent messages (180, 200ok, etc). the impact here is that the fr_inv_timer eventually fires even though the call has been answered. Note: this only happens when the call is destined for the device behind the NAT.<br>

<br>
Any ideas.<br>
<br>
Perhaps an explanation on how the tm module does transaction manager.<br>
<br>
RFC3261 states that transaction matching is done based on the via branch parameter.<br>

it is the way tm does it. Can you paste the sip trace of such situation? It will help to troubleshoot.<br>
<br>
Cheers,<br>
