[Shehzad]

Hello,
I have attached a whole trace as below. 
http://n2.nabble.com/file/n2818688/MAILING_10.10.2.5_ACK_sipp.log
MAILING_10.10.2.5_ACK_sipp.log 

Some IP as referenced in the above trace are as below:
<Caller_IP> : IP address of Caller Gateway
<Opensips_local_IP> : IP address of Opensips Server
<Firewall_Public_IP> : IP address of Firewall 
<Called_IP> : IP address of provider

Thanks,
msp
