Static sound on outbound calls

12 Sep 2012

      Hello All,

I have been using FreeSWITCH over the last two years on both inbound and
outbound dialing.

I have a problem with Outbound calling.

This does not occur all the time, but often enough for us to be
concerned.

We have an IVR system that make an outbound call to our client and
process the call flow using DTMF.

Often times when user answers the call, there is nothing but static
sound. It does not respond to any DTMF, and does not play any sound file
either. 

It just hangs there with little static sound in background. 

I have consulted my SIP provider but they have no idea either.

Any one has any idea what might be causing the issue?

Thank you in advance.

Best regards,

Phil H. Kim
