Hello Daniel,

in case the same "hardware id" (registration name) is used to register both of the softphones, it is not possible for the PBX to distinguish between this two registrations while controlling it via RCC.

The PBX can handle multiple devices registered on a user object by using different "hardware id" for each registration, but can not handle multiple registrations on the same "hardware id".

Controlling the both registrations is only possible locally via EpSignal, but not remotely via PBX/RCC.

If you want to control two softphones on same user via RCC, you must create two softphone devices on this user and use different on different PCs.

Would it be a solution for your case?

Best Regards

Andreas Fink
