Stefan,

I had the same issue and eded up storing in cachedb info about current calls with source - destination info and in a case of re-invite taking actual destination from there and not from a SIP packet directly.
You can use in-dialog variables for this as well, I'm using cachedb for historical reasons.

Cheers,
Ihor

Hi !

I have the following setup.


caller (A) from outside .operator -->  opensips --> alcatel OxE ==> Set.


When an outside caller calls in the opensips relays out the calls to the OxE’ set.

Oxe respons to the A thru opensips all transactions and the initial dialog is created …

Then oxe sends an reinvite to the opensips to give its correct c= in  the sdp.  (OxE has a cpu with o= and and c= point of some InTIP card rtp points … in the sdp

********  Heres the problem ….

Opensips relays this reinvite back to the (A)  wich is totally wrong this re-invite should goto opensip to fix the rtp endpoints ….

How can I prevent the Opensips to reply the reinvite to the A point …  Shall I issue a new topoly-hiding() or ….  (Can there be two of them. )
Any help would be very appreciated …


Kind Regards …
