[Freeswitch-users] How to change Music-on-hold while digit_bind_action is used ?

[Michael Collins]

Hi Julien,

Welcome to FreeSWITCH! Glad you like it.

To answer your initial question: yes, what you are trying to accomplish is
definitely possible. However if you want the caller ("A" in your scenario)
to press only a single key then you can't use bind_meta_app (BMA). BMA
requires two key presses: * and one other DTMF. That's why your scenario
requires ** to trigger.

If you want to have only a single key press trigger your Lua script then
you'll need to use bind_digit_action (BDA). It's a bit more complicated,
but it's also more powerful. Start here:
http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_bind_digit_action

You should be able to match on just a single * key press. The dialplan will
have something kind of like this:

<action application="bind_digit_action"
data="my_realm,*,exec:lua,send_email.lua,a,peer"/>
<action application="digit_action_set_realm" data="my_realm"/>

Tinker with that and remember the standard
disclaimer<http://wiki.freeswitch.org/wiki/Reporting_Bugs#Standard_Disclaimer>before
you tell me it doesn't work. :)

Have fun!
-MC
