Re: [OpenSIPS-Users] Does OpenSIPS support Request-Disposition: no-fork in INVITE message?
Hi Richard,
I really appreciate your help!
However, the initial problem is to avoid the forking for the scenario you
mentioned (no matter if it is serial or parallel) if the INVITE is coming from
the GW with Request-Disposition: no-fork. The issue is with the “to tag”
parameter:
https://www.opensips.org/Documentation/Script-CoreVar-3-2#toc90
This is read only and also Bogdan does not recommend to play with this:
http://lists.opensips.org/pipermail/users/2022-October/046318.html
Here is my original question, I hope you have some idea for this.

I'm not looking back to see the old conversation so forgive me if I'm
answering the wrong question here. So, I think you want to send the call to a
customer, say at their desk. If they don't answer then send the call to, for
example, their cellphone. In that case you would want serial forking rather
than parallel forking.
(and im not testing this so may miss something here but in general)

Hi Bogdan-Andrei,
I know this is an old topic but customer is complaining.
How is it possible to configure the call forwarding no answer without forking?

Hi Bela,
As per prev email, there is nothing to be supported by OpenSIPS, just don;t do
forking in your cfg, nothing more.
