I have a Polycom phone that has two extensions registered to it, let’s say 200 & 201.

Is there anyway to code Asterisk to show BOTH lines are busy when either 200 or 201 are in use?

Reason is that my Polycom phones will show the presence info via BLF red light, but I would have to have 2 separate entries in the monitoring phone (one for each extension), even though it’s only one device.


Figured it out:

exten => 200,hint/SIP/200&SIP/201&etc.

Fairly easy actually!
