Hi all, I was looking for a solution to set a dedicated From URI in OPTIONS requests to a specific dispatcher target.

ds_ping_from ( https://www.kamailio.org/docs/modules/devel/modules/dispatcher.html#dispatch...) applies globally, why I needed the granularity of a single target.

With these changes to the dispatcher module I get what I need: https://github.com/kamailio/kamailio/commit/3f9c38be11416f7abe5c4448088ba66d...

I can just add an attribute to the others, e.g. instead of

*1 sip:127.0.0.1:7070 http://127.0.0.1:7070 0 1*

something like:

*1 sip:127.0.0.1:7070 http://127.0.0.1:7070 0 1 ping_from=sip.custom.com http://sip.custom.com*

When the ping_from attribute is not specified, the general ds_ping_from applies and is used.

This would save me from a solution like intercepting the outgoing OPTIONS and manipulating the From header.

Does this approach make sense? Are there other ways already available to achieve this?

Thanks, Giacomo
