5200 series phones & compression

[cl8ton]

Hello-

Can anyone confirm whether or not the entire 5200 series of Mitel ip phones supports G.729 compression?

thanks

very good, thank you.

Ian - can you tell me if its possible to change the 3300 compression default from G.729 NO to G.729 YES? I'm trying to see if that has been set up correctly in our controller and I can't seem to find where that is set at.

thank you-

Carla

by default your IP phone to Ip phone (5215 +) calls on the same internal network operate G729 compression by default.

if you are using compression over an IP network and want to compress the TDM side of things go to route assignment and set compression to use for the routes you want to you compression on.

However for this to work you need to install DSP modules and have some compression Licenses on your controller activated also.

You sure about that? I thought default is uncompressed unless you set up the compression zones and add the phones to them.

By default the phone don't compress. You are right in saying that you need to set up compression zones. If any two phones communicate and they are in different compression zones, the call will be compressed. If you have two phones in the same compression zone, you could enable interzone compression.

This is only valid when you are using compression zones other than the default which is 1. You cannot do interzone compression in compression zone 1.
