Playing Incoming Call Ringing through RJ-9 Headset

Only the C435HD phone is currently supported.

Support has been added for ringing via an RJ-9 headset on the C435HD phone.

The figure below shows the RJ9 headset port:

Admins will use parameter audio/stream/ringer/0/audio_device to specify which device will ring when a call comes in.

Two new configuration values have been added:

TYPE_HEADSET (regular headset)
TYPE_RJ9_HEADSET

The parameter can be configured via the Device Manager as well as via SSH command. The parameter is also available in the template which can be applied to multiple phones via the Device Manager.
