[OpenSIPS-Users] PUBLISH from External service

[Maksims Deņisovs]

Good day, community.

I have a scheme: A – O – C, where
A – hardware phone with BLF buttons
O – opensips
C – external server

Working scenario:
A sends subscribe (for some number, for example 123456789 at opensips) events to opensips.
C sends publish events to O about number 123456789 status (busy, available, etc)
O sends notify events to A about 123456789 number status.

What should I use for this scenario? The same scenario is described in https://opensips.org/docs/modules/2.4.x/presence_callinfo.html, but what should I use for “External publishing”?

Will be glad to receive any response for this :)
Thanks!
