Hi Grant,

Check inside your JS script for a value.  It is waiting for the hangup event to run so DTMFvalues should exist.

You <action application=”log” … may be running before the DTMF is received.

Subject: [Freeswitch-users] Received DTMF not available

Hello,

I’m originating calls from Freeswitch to remote destinations.

When the destination answers the call (wait_for_answer) I ask the destination for some digits.

        <action application="play_and_get_digits" data="6 8 2 5000 # ${prompts_directory}/ask_and_collect.wav ${prompts_directory}/invalid.wav dtmfInput \d 2500"/>

        <action application="set" data="api_hangup_hook=jsrun $${scripts_directory}/collect_data.js ${internal_reference} DTMFInput=${dtmfInput}"/>

        <action application="log" data="INFO The caller entered the following code for verification: ${dtmfInput}" />

It happens quite often where the variable $[dtmfInput} doesn’t have a value, even though I see the console output in Freeswitch receiving the DTMF events.

I’m using RFC2833 mode.

Any ideas why this happens?
