Hi,
I have a specific scenario where I need SIPp to send with a source port
of TCP(5060) and destination port TCP(5060) on multiple loopback interfaces.
So far, I have been unable to achieve this. It's fine in UDP using the
below command:
sipp -sn uac 10.248.1.1 -i 10.249.130.10 -p 5060
08:40:24.227505 IP 10.249.130.10.5060 > 10.248.1.1.5060: SIP: INVITE
sip:service@10.248.1.1:5060 SIP/2.0
But as soon as we switch to TCP, the source interface changes to the
interface for the route rather than being the loopback. I think that
this is because a listener is already created on the loopback on port 5060.
sipp -sn uac 10.248.1.1 -i 10.249.130.10 -p 5060 -t t1
08:41:33.623386 IP 192.168.0.10.5060 > 10.248.1.1.5060: Flags [S], seq
3336473269, win 29200, options [mss 1460,sackOK,TS val 1099329694 ecr
0,nop,wscale 0], length 0
Is there any way to achieve what I am attempting with SIPp?
Many thanks,
Mark
