Thx John !!
Hmm I found now on voip-info.org a lot of Beta releases which should fix my
problems... Kind of strange whats going on with Grandstream devices and their
firmware ... If you install the latest "official" release you can expect a
few troubles with Asterisk 1.4.11 (one way audio --> randomly, dropped
calls). So you have to install the BETAS whether you want or not...
That you have to use unique ports is a rumour and not SIP standard. As John
said --> IP:Port must be unique . I definitely not understand why I should
use random ports.
> I`m using several GXP2020 phones with newest Firmware 220.127.116.11.
I had issues with phone locking up using 18.104.22.168. I've now gone to 22.214.171.124
and have eliminated that.
> Asterisk Version: 1.4.11.
Me too. Still testing 1.4.13 on a non-production system.
> I use on every phone the 10000 as local port and in the rtp.conf
>From my knowledge of IP I don't think this is a problem since the
address/port would be unique. However the example config I originally had
from Grandstream indicated that each phone should use a different port and
recommended to use the random port option on the phones. I have since
assigned the port number on each phone to 10000 plus the extension number.
This was done to create a unique port number and to help with
troubleshooting when using Wireshark or tcpdump. I set this in the config
file for each phone.
