asterisk users - Jan 2008 - Busy notification with call limiting by GROUP_COUNT()

Hello all,

I was wondering what will be the "proper" way to manage BUSY state 
notification in presence once call-limit, incominglimit and all those 
settings are gone.

I'm using GROUP_COUNT for call limiting in Asterisk 1.4.13 but I have no 
idea how to set up the settings needed for BUSY notification to work as 
I want it to.

Basically, I want to disable call waiting (this is done by the 
GROUP_COUNT() check in dialplan) but don't want to limit the number of 
outgoing calls per user at all. I want the user to be presented as busy 
if he has at least one call active, be it incoming or outgoing. How 
should I set things up to achieve this?

Thanks in advance. Best,
Peter

I have a very similar need. We are using call queues and would like to
have only 1 call presented to our trouble call reps at a time, but would
like to give them the ability to initiate an outgoing call on a
different line (even while on an incoming call). We are using Aastra
480i SIP phones. 

I have read that app_groupcount and setgroup may be the way to handle
this but the wiki is confusing.

Can someone suggest an approach (preferably one currently in use)? We
are using Asterisk 1.4.17.

You could always set the Aastra to allow incoming only on line 9 so a 
second call shows up as busy and let them call out on 1-8.  That does 
it completely outside Asterisk but should work just fine.
