[Users] SIP Invite Header Modification

[Gene Cohen]

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 at 69.60.182.155:5060 SIP/2.0 

none of these work : 

	INVITE sip:7035470041 at 69.60.182.155:5060;dtg=SIP SIP/2.0 
INVITE sip:7035470041;npdi=yes;@69.60.182.155:5060;dtg=SIP SIP/2.0 
INVITE sip:7035470041;cic=5119;@69.60.182.155:5060;dtg=SIP SIP/2.0 
INVITE sip:7035470041;cic=5119;npdi=yes;@69.60.182.155:5060;dtg=SIP SIP/2.0 

	 

	thanks,
