If anyone can help me on this one thanks before hand, i have a setup on
kamilio and everything has been working fine, i need to interface with a
huge carrier and they don't like the way kamailio sends the invites so i
need to implement stric routing .
now when kamailio sends an invite it goes like
+0.000140 Kamailio:5060 -> CarrierIP:5060
INVITE sip:XXXXXX@Kamailio IP SIP/2.0.
Record-Route: <sip:Kamailio
IP;lr=on;ftag=as4640f260<sip:54.236.192.19;lr=on;ftag=as4640f260>
.
Via: SIP/2.0/UDP Kamailio IP:5060;branch=z9hG4bK9156.eeb6fbf7.0.
Via: SIP/2.0/UDP Kamailio IP:5060;branch=z9hG4bK7aeceb75;rport=5060.
Max-Forwards: 16.
To: sip:XXXXXX@KAMAILIO
IP@54.236.192.19<sip:85630573108863792@54.236.192.19@54.236.192.19>
.
and they wanted to receive it like this
INVITE sip:XXXXXX@CARRIER IP;user=phone SIP/2.0.
Via: SIP/2.0/UDP KAMAILIO IP:5062;
From:
<sip:XXXXXX@KAMAILIOIP:5060;user=phone>;tag=514594693-3792808143-4087363760-57672641.
To: <sip:XXXXXXXX@CARRIERIP;user=phone .
Call-ID: 8517ac46cfa811e2b038a0f3c1037003(a)204.2.202.12.
CSeq: 1 INVITE.
I dont know how to achieve this in kamailio, i am working fine with several
carriers using loose routing
here is my config any help is greatly apreciated
