[SIPForum-discussion] FW: querry related to SIPp

[dushyant]

Hi all,

 

Can anybody help me in resolving a issue related to SIPp? In an IMS call
scenario I need to preserve the record route received in 200OK and use the
same to form Route header of ACK. I have made the following changes in the
xml files but instead of using the values received in Record-Route of 200
OK, it's is using some default value. The received message (200OK) and xml
portion are attached.

 

UDP message received [481] bytes :
