[OpenSIPS-Users] Delivery Status Notification (Failure)

[johan de clercq]

What I can do is use multiple instances. 

Instance 1 : do header changes and rewritehostport to instance 2
Instance 2 : do b2bua scenario and route to instance 3
Instance 3 : do the actual work. 

KR,

The refer-to header looks like this: 

"<sip:81005 at psx.democon.be;user=phone?Replaces=bf0cbd3f-33c16b5c-ac88f411%40
213.125.208.178%3Bto-tag%3DHjDD97H3getUQ%3Bfrom-tag%3DE23BB509-F55C93D6>"

And I think that in order for the scenario to work, it should have the
following layout :

<sip:81005 at psx.democon.be>

So that's the manipulation that I want to do :

Extract part before ; and add >

Johan,

The REFER request will never get into your script as it will be absorbed and
handled by the b2b module - actually will not see any sequential requests
for a call that was pushed into b2b.

What kind of manipulation you want to do over the REFER-TO hdr ?
