Jabber for Window 10.6 which is currently in our Early Adopter Program trial and targeted to release on January 22nd, 2015, intends to add the following functionality, perhaps 10.6 will meet your needs?
Do Not Disturb
Call alerts and ringers are suppressed when your presence is Do Not Disturb, or in any red presence
state. If you receive a call while in Do Not Disturb, you still see a missed call notification on your client.
Call Notifications on Other Device
For users who do not want to interrupt their work to answer the phone, you can now disable incoming
call alerts, which requires the call to be answered on a desk phone or a headset.
Mute Before Answer
When you are joining a call, you can now mute your phone before you connect to the call.
Audio Device Selection
You can select your preferred headset or other audio device directly from chat windows. A new option
allows you to open audio options in the Jabber client, and select your microphone, headset, and ringer
preferences.
Ring on All Devices
You can hear incoming Jabber calls and alerts on your computer speakers and all connected devices.
Even if your headphones are plugged in, when you receive a Jabber phone call or IM alert, the sound
is played in both your headset and through your computer speakers. This feature is enabled by default,
but users can change their ringer and alert preferences in the Audio tab of the Options menu.
