Re: [Users] SIP Invite Header Modification - sr-users

      Gene,
subst() works only on the header, so the first line is not covered by 
this function. subst_uri() works only on the RURI (from the first line).
so try:
    subst_uri("/sip:(.*)$/18888888888@xxx.xxx.xxx.xxx/")
To header is not recommended to be changed since it's used to 
transaction matching - anyhow it has no purpose in routing.

Bogdan,
I have no problem changing to To:  but the INVITE doesn't match evn though I
use the same code.
I tried subst and subst_uri  - here is the code:
if (subst("/^INVITE(.*)$/INVITE sip:18888888888@xxx.xxx.xxx.xxx;/") )
{
   	log("URISUBSTITUTED");
   		
   }
   else
   {
   	log("INVITE NOTSUBSTITUTED");
}
if (subst("/^To(.*)$/To: sip:18888888888@xxx.xxx.xxx.xxx;/") )
{
   	log("TO SUBSTITUTED");
   		
   }
   else
   {
   log("TO NOT SUBSTITUTED");
}
Thanks,
Gene

Hi Gene,
As I see, you actually want to change the first line of INVITE and not 
the headers..for changing the ruri you have the subst_uri() function 
(regexp based) in textops module:
   http://openser.org/docs/modules/1.0.x/textops.html#AEN141
make a regexp to get rid of the ruri params.

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 :
 INVITE sip:7035470041@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,

 gene
