[Freeswitch-users] Freeswitch as IVR Tester

I am trying to use FS as an automated test platform to send calls into an IVR system (also FS) and test the various call flows.
I am using node.js to control the tests over ESL.
I am using ‘originate xxx &park()’ to initiate the test call to the IVR.
Then ‘detect_speech’ with pocketsphinx to listen for key phrases in the prompts from the IVR (‘followed by hash’) etc.
So far so good - although I haven’t tested many different prompts yet.
I am then trying to use ’send_dtmf’ to navigate the IVR menus.
I am having some problems with this.
After the ‘send_dtmf’ is requested, nothing happens.
I read on a different post that it will work if you do a ‘playback’ before ‘send_dtmf’.
I tried this, and yes, ‘send_dtmf’ now does something - but not what is expected.
The CHANNEL_EXECUTE_COMPLETE event for ‘send_dtmf’ returns instantly ( e.g. 1 ms after the associated CHANNEL_EXECUTE event) rather than after the DTMF is sent, which messes up my state machine.
Also the IVR system does not react to the DTMF.
I made a test call to an x-lite instead of the IVR, and could hear the DTMF but it was distorted.
Any help greatly appreciated.
I am using 1.6.9 (installed from rpm’s) on centos 7.
