[asterisk-users] VoIP over 3G/4G Data

[Tech Dude]

What are the recommended settings to successfully implement VoIP over 3G/4G
data connection. Assume we are talking about using Polycom phones, and the
3G/4G data connection comes from a Cradlepoint router that is plugged in
with AC power and has high gain antennas. The device will be stationary, so
we will not have to worry about tower handoff’s breaking the connection.
This will be for fixed wireless.



I have read to use G.729 codec, and TCP for signaling to bypass firewalls.
Besides that, what other settings are recommended?  Changes in MTU? Changes
in voice payload ms? Is there a better codec to use? Header compression?
