asterisk users - Nov 2007 - Fwd: Re: Grandstream GXP2020 + Asterisk 1.4.11

Hi, 
I'm using a GXP2000 (that's sharing the same GXP2020 firmware file) with
the latest 1.1.5.10 beta release. It's working since a week and seems
working very well. Before I was using the 1.1.5.3 and I had no problem. 1.1.4.xx
versions, instead, are not performing like that one (audio, deadlocks and other
minor issues).
You can find a lot of info and old firmware versions at this link:
http://www.grandstream.com/BETATEST

Some feedbacks about firmware versions here:

In the RTP port configuration I'm using the fixed 5004 and I think that you
have to change it or use a random port only on some specific firewall/network
topologies.
My Asterisk version is the 1.4.12.

Thank you and bye.
