[OpenSER-Users] Loop Detection

I have a problem. I'm taking INVITES from a PortaSIP proxy and handing it back with a new request URI and To: header; however, their loop detection algorithm is calling this a loop. Is there a way to fix this from within OpenSER? I'm assuming my proxy would have to send an INVITE with a completely new branch tag and From tag? 10 Dec 14:52:30.831/GLOBAL/b2bua: SENDING message to 206.71.169.114:5060: INVITE
