I am working with a VoiceGenie SIP VXML server which is very sensitive to SIP headers on INVITE - if the format is not just so, it cannot handle the calls.
 
I want to use openser to mask this problem by sending a consistent SIP INVITE that the VoiceGenie can handle.
 
Does anyone have any advice on how to do this?
 

This (simple) INVITE header works :

        INVITE sip:7035470041@69.60.182.155:5060 SIP/2.0

none of these work :
