[asterisk-dev] Need to run an AGI from dialplan only upon call hold

[Marco Signorini]

Hi.

The link reported by Lenz refers to the frame_trigger patch we implemented.
The idea is to define a set of control frames that will trigger specific 
dialplan calls when found on the channel where the filter is applied.
In QueueMetrics this could be used to write to the queue_log some 
specific events used by the engine to retrieve, for example, hold and 
unhold events on the agent's channels.
I never tested the patch in a production environment but, as far as I 
remember, I was able to have events written in the queue_log in my test 
environment.

As told by Lenz the code was not included in the main trunk because it 
allows arbitrary code execution on the same thread is handling the 
control packets in Asterisk.

You sad you already tried to use it but without success. Could you, 
please, tell me what's the problem you had?

Thank you and regards,
Marco Signorini.
