[Asterisk-Users] Call Queue with no agents -> Congestion or voicebox instead of MOH?

[Jan Baumann]

Hi all,

I have successfully set up a call queue with agents and agentCallbackLogin.

Works fine, but if no agent is logged in incoming callers get
music-on-hold forever (or until some timeout).

Is it possible to play congestion tone without answering the call (and
thus causing costs to PSTN callers) or send them to unvailable-mailbox
directly to leave a message if no agents are logged into the queue?

Thanks and best regards,
Jan
