I’‘m testing this in an admittedly quick-and-dirty setup, and here’‘s what I’'ve got:
phone is SIP/2200
extenstion is the DID from a PRI that goes to SIP/2200.
When I dial the DID, I get “on the phone” as a status indicator, when I dial out from the phone it works as well.
However internal calls (extention 2500 is voicemail for example) it does not change the presence.
Is this how it should work or am I missing something?
