I have 5 queues with 5 users in each queues.
Before I used PBX Asterisk with function BLF and PickUp calls from queue.
For SIP-T22P DSS button: Light - one or more agent in queue, blinking - incoming call in queue, press - pickup call.
Right now I move to S300 and I want to use BLF status for queue and pickup first call in queue.
This function added to asterisk in 1.8.5 version. How I see - you just need add this in extensions.conf
Example 2: Queue with Dynamic Users: Note: we use '_' in the queue names, and '-' for the context [trusted] exten => 8501,hint,Queue:itg_queue ;Provide a hint for the queue exten => _**8501,1,Pickup(itg@trusted) ;Pickup the queue exten => 8501,1,Goto(itg-queue,itg,1) ;Ring the queue [itg-queue] exten => itg,1,Queue(itg_queue,crhH,,,127)
