I have to change the uas.xml and uac.xml in SIPP such that it will support returning 2 headers or 2 via's . For example :
ACK sip:[service]@[remote_ip]:[remote_port] SIP/2.0
Via: SIP/2.0/[transport] [local_ip]:[local_port]
**Via: STACKOVERFLOW**
From: sipp <sip:sipp@[local_ip]:[local_port]>
To: sut <sip:[service]@[remote_ip]:[remote_port]>
Call-ID: [call_id]
CSeq: 1 ACK
Contact: sip:sipp@[local_ip]:[local_port]
Max-Forwards: 70
