Thanks Guys, I'll be trying this. Do you know if I
can use AVP or vars
as parameters for these functions?
|encode_contact(encoding_prefix)
||decode_contact()|

The best would be to tell the providers that they should fix their
systems.
As a workaround you could try encode/decode contact functions:
http://sip-router.org/docbook/sip-router/branch/master/modules_k/siputils/s…
IIRC these functions may cause strange results if you do other
contact rewriting too (e.g. fix_nated_contact).

Guys,
I'm successfully using a Kamailio + RTPproxy setup in bridge
mode with
most of my Gateways. My setup includes two different interfaces
one with
a public IP and teh other with the private IP.
Now I'm facing some slight issue. Some providers won't accept my
calls
(or calls will have some strange behavior) if the Contact header
has an
IP out of immediate range.
I tried to use fix_nated_contact() function but as per my
topology, this
function will not change the contact header because the IP is
already
the one on the interface.
Example:
U 192.168.200.X:5060 -> 192.168.200.Y:5060
INVITE sip:111160911097@192.168.200.Y SIP/2.0.
Via: SIP/2.0/UDP 192.168.200.X:5060;branch=z9hG4bK096baacc;rport.
From: "Uriel Rozenbaum"
<sip:60911100@192.168.200.X>;tag=as32794d5e.
To: <sip:111160911097@192.168.200.Y>.
Contact: <sip:60911100@*192.168.200.X*>.
U 200.A.A.A:5060 -> 200.B.B.B:5060
INVITE sip:898960911097@200.B.B.B SIP/2.0.
Record-Route: <sip:200.A.A.A;r2=on;lr=on;ftag=as32794d5e>.
Record-Route: <sip:192.168.200.Y;r2=on;lr=on;ftag=as32794d5e>.
Via: SIP/2.0/UDP 200.A.A.A;branch=z9hG4bK5222.14fbf4f7.0.
Via: SIP/2.0/UDP
192.168.200.X:5060;received=192.168.200.X;branch=z9hG4bK096baacc;rport=5060.
From: "Uriel Rozenbaum"
<sip:60911100@192.168.200.X>;tag=as32794d5e.
To: <sip:111160911097@192.168.200.Y>.
Contact: <sip:60911100@*192.168.200.X*>.
Is there any way to let know Kamailio the outgoing IP I'll be
using and
fix the contact accordingly?
I can trigger this change after I know the destination IP.
Thanks!
Uriel
