asterisk users - Oct 2004 - Zyxel P2000W web interface?

Hey,
I've got this phone, and it's working allmost perfectly ;p

Firstly I get some unknown codec errors in asterisk so the first half 
second when I make a call is blurry, after that it's just fine.
Then it's that menu selections won't work.
According to www.voip-info.org/wiki-Asterisk+phone+Zyxel+P2000W

I can configure DSP settings in the web interface, but the web interface 
I get there's no such option, nor on the actual phone, anyone know of 
any clever workarounds?
Thanks.

Hi Andreas,

Great. There are not a lot of people sucessfully using this phone with 
asterisk. Would you care to elaborate on details like asterisk version, 
P2000W firmware used (see Information page in web interface), sip.conf 
entry, etc? :)
Have you tried calling some SIP softphone and being called by some SIP 
softphone? No problems?

The web interface significantly changed with each firmware version so far. 
I am currently using WJ.00.0f
which includes the DSP settings. The Wj.00.07 which came with my phone had 
less settings available.

Afaik, the firmware is freely available (e.g. 
http://www.zy.com.pl/ftp/MIRROR-FTP-ZYXEL/P2000W/firmware/ ) but read the 
update procedure very carefully. A power loss at the wrong moment might 
render the phone inaccessible.

Cheers,
