[Freeswitch-users] Function - drop_dtmf

[Magnus Kelly]

Hello Guys,

Couple of questions on the dtmf masking function that was created/extended
recently - is it possible to use half way through a call ? - in terms of
invoking the DTMF masking by initiating dtmf as in the below dial plan,
and associated features.xml entry - would the call be able to start as
normal and then on demand mask dumf?

<extension name="dtmftest">

<condition field="destination_number" expression=""^(\d+)$"">

<action application="export" data="dialed_extension=$1"/>

<action application="bind_meta_app" data="1 a s
execute_extension::stopdtmf XML features"/>

<action application="set" data="call_timeout=30"/>

<action application="set" data="hangup_after_bridge=true"/>

<action application="set" data="continue_on_fail=true"/>

<action application="bridge" data="sofia/$***@10. <***@10.113.0.98>x.x.x"/>

<action application="answer"/>

<action application="sleep" data="1000"/>

</condition>

</extension>


and an entry in features.xml as in -

<include>

<context name="features">



<!-- StopDTMF on the B leg (Overwrite) -->

<extension name="stopdtmf">

<condition field="destination_number" expression="^stopdtmf$">

<action application="export" data="nolocal:drop_dtmf=true"/>

<action application="export"
data="nolocal:drop_dtmf_masking_digits=d"/>

</condition>

</extension>

I guess then I would need an alternative bind digit to turn the feature
feature off again? Is this possible or is this only selectable at bridge
time? Any thoughts?


Thanks

Magnus
