[Sark Mobiles]

Hello,

We installed and configured Freeswitch on CentOS as per the steps provided
in below link,

https://freeswitch.org/confluence/display/FREESWITCH/CentOS+7+and+RHEL+7#CentOS7andRHEL7-CentOS7andRHEL7-Stable

This is the status -
* Users are getting registered
* When User A calls User B, B gets a ringtone and is able to answer the call
* A sees that the call is connected but there is no audio for either A or B.
