#156 SIPp does not bind to IP address given in "-i" option

[Vishwas P G]

When i run a sipp tcp call, the server is getting the primary ip address and not the ip address given in the -i option. Because the INVITE, FROM and Via contains the IP address given in "-i", the calls are failing.
This is happening for TCP calls and from version 3.5.1 onwards. I dont see this issue for 3.4.1
Please see the below commands run. Any input to resolve this?? Thanks in advance.

./sipp -sn uas -i 10.54.56.134 -p 6810 -m 1 -t t1
./sipp -sn uac -i 10.54.56.241 -p 6820 10.54.56.134:6810 -m 1 -t t1 -trace_err

This is the netcat output:

Connection from 10.54.56.4 port 6820 [tcp/*] accepted
INVITE sip:service@10.54.56.134:6810 SIP/2.0
Via: SIP/2.0/TCP 10.54.56.241:6820;branch=z9hG4bK-2202-1-0
From: sipp sip:sipp@10.54.56.241:6820;tag=2202SIPpTag001

So if you see it should pick 10.54.56.241 as the IP but instead picks the primary IP of the system 10.54.56.4
