I have a Freeswitch server in the cloud with three SIP providers, DIDForSale and IPKall for incoming and CallWithUs for outgoing.

When someone calls me, thru either incoming provider I hear everything clear but i'm choppy to the other end.
When I make an outgoing call, audio is great in and out, also if I do an echo test my audio is perfect.

I have check the freeswitch.log and its not transcoding  (grep transcod freeswitch.log) which was a suggestion from #freeswitch

also added 

verbose_sdp=true 
<param name="vad" value="disable"/>
<param name="suppress-cng" value="true"/>

with no success, any thoughts?


Regards,
