[SIPForum-discussion] how to add Via header field in the excistingINVITE request

[dipanjan.dutta at aricent.com]

Hi Gokul,

A node in a SIP signaling path can add a Via header with its own address 
in order to let the subsequent nodes know that which path the return 
message may traverse. So it's one's own address and not the address of 
say, the next hop.

thanks,
Dipanjan
