[SR-Users] SipML5-Kamailio+RtpEngine-ThirdpartySipServers- Not All SIP Servers are working

Thu Apr 16 18:24:18 CEST 2015 

Can someone help me please …

I am using this setup .  Sipml5 webrtc client(chrome) -----> Kamailio with
RTP engine ------> ThridpartySip Server

kamalio will act as mediator between webRTC client and NonWebRTC sip server
.

User will be  registered on sip server  and calls will be terminated to
PSTN .

This setup is working fine with one thirdparty sip server but not working
with other SIP server .

First server ( working ) is happily replying INVITE request and reponding
with "TRYING "   .
But Second SIP server never reply to kamailio for  INVITE requests and
kamailio keep sending SDP and finally on SipML5 it shows "request timed out
" Ports are open on Firewall .

SIP Server 1: 192.168.102.237

SIP Server 2: 192.168.87.101


Kamailio IP : 172.17.185.46

Client PUblic ip :  79.207.241.94
