Thanks Guys, I'll be trying this. Do you know if I can use AVP or vars as parameters for these functions?<br><code class="function">encode_contact(encoding_prefix)<br></code><code class="function">decode_contact()</code><br>

The best would be to tell the providers that they should fix their systems.<br>
<br>
As a workaround you could try encode/decode contact functions:<br>

<br>
IIRC these functions may cause strange results if you do other contact rewriting too (e.g. fix_nated_contact).<br>

Guys,<br>
<br>
I'm successfully using a Kamailio + RTPproxy setup in bridge mode with<br>
most of my Gateways. My setup includes two different interfaces one with<br>
a public IP and teh other with the private IP.<br>
<br>
Now I'm facing some slight issue. Some providers won't accept my calls<br>
(or calls will have some strange behavior) if the Contact header has an<br>
IP out of immediate range.<br>
<br>
I tried to use fix_nated_contact() function but as per my topology, this<br>
function will not change the contact header because the IP is already<br>
the one on the interface.<br>
<br>
Example:<br>
U 192.168.200.X:5060 -> 192.168.200.Y:5060<br>
INVITE sip:111160911097@192.168.200.Y SIP/2.0.<br>
Via: SIP/2.0/UDP 192.168.200.X:5060;branch=z9hG4bK096baacc;rport.<br>

To: <sip:111160911097@192.168.200.Y>.<br>
Contact: <sip:60911100@*192.168.200.X*>.<br>
<br>
U 200.A.A.A:5060 -> 200.B.B.B:5060<br>
INVITE sip:898960911097@200.B.B.B SIP/2.0.<br>

Contact: <sip:60911100@*192.168.200.X*>.<br>
<br>
Is there any way to let know Kamailio the outgoing IP I'll be using and<br>
fix the contact accordingly?<br>
I can trigger this change after I know the destination IP.<br>
<br>
Thanks!<br>
