[Asterisk-Users] Snom 'virtual' extension monitoring?

[Remco Barende]

Hi list!

I'm working to replace a PBX with group ring indication.

On the current PBX each phone has 3 buttons with a light to identify an 
incoming call ringing for a certain group. For example if the phone is 
ringing at sales a led lights up to indicate a call coming in on that 
group (but that phone is not ringing). Other departments can hear the 
phone ringing in the other dept. even though it's not their own phone that 
is ringing.

Can I use the programmable buttons on a Snom phone to achieve a similar 
thing?

I was thinking of creating a virtual extension for each group (like sales, 
admin, support etc). For each department I include that extension to 
'ring'.

The snom would monitor this extension for incoming unanswered called and 
people in another dept. can answer the call by just picking up the phone.

Is this possible? Can a virtual extension be created this way and can it 
be monitored in the way I was thinking of?

This would be an alternative to the groups feature of *, because I don't
think you can use the buttons and lights on the snom phones in the way I
described above.
This method is preferred because with the group function in * you are 
either ringing every phone in the department driving you crazy when there 
are many phones, or you have some phones ring and call pickup is more 
complicated.

Thanks!
