[Freeswitch-users] sip stack problem in fsw

[Anthony Minessale]

Asterisk is not capable of async RTP and CNG so it's lack of
functionality is a feature in your case and it's probably the same
platform your provider is using.

Sending RTP for no reason when you are not talking is somewhat silly right?

Are you actually remaining silent for that period of 5 min?
Did you get the trace and prove it?

you can do the following if you wish to mimic asterisk

add this to your sofia profile in internal.xml

<param name="supress-cng" value="true"/>

restart the profile or FS

this will tell your phone and your isp not to use cng
