ZyXEL P2000W

Introduction

ZyXEL P2000W is a cordless WiFi phone. It operates on an 802.11b wireless network and acts as a SIP client. It has built-in PPPoE support and can use G.711 or G.729 codecs.

Hardware

Appears to be same the hardware as the Pulver Innovations WiSIP phone.

Firmware

- Earlier than WJ.00.0f
Early revisions of the firmware were spectacularly flakey; most phones still ship with the initial firmware. For reliable operation with Asterisk, the phone must be upgraded to WJ.00.0f or newer. Updated firmware can be found here.

As of writing (14 March 2005), you must use Internet Explorer to perform the update — updates via Firefox will hang at the 99% mark.

- WJ.00.10
Warning: Firmware WJ.00.10 prevents using a P2000W with Asterisk. This new firmware implements VAD/CNG, however these features are always enabled. Asterisk does not support audio streams with VAD enabled. Upgrading from WJ.00.0f is one way - it is not possible to downgrade to a previous firmware level.

(above Warning may or may not be true for some - I upgraded to WJ.00.10 and have no problems using the P2000W with Asterisk!)

- WJ.00.11
The WJ.00.11 firmware fixes a lot of bugs and for me this is the first usable version! WiFi profiles work and RFC2833 works correctly so I can use DTMF after the call connects. I have had no problems with Asterisk and G.711/G.729. The phone is still a "simple" WiFi phone, but it works better than most now....but still missing a lot of advanced features. Still no NTP for time, web configure still has issues, etc.

- WJ.00.13
This firmware contains some cosmetic fixes (voice mail icon changed) as well as some interop fixes (option packet parsing, sends ack to correct port).


Troubleshooting (Matthew1471's Guide)

- I am hearing no Asterisk audio or ringing
First thing, make sure you've changed the codec away from G.729. G.729 is a great codec but Asterisk only allows pass-through calls (i.e. from one G.729 SIP phone to another) change the codec!

- The phone registers then disconnects
This is a weird bug, the symptoms for this appear to be when you are trying to Ad-hoc the phone AND have bridged 2 connections to try and give it access to the internet.. This is either due to the phone giving out poorly structured packets or due to a bug in the Windows XP bridging function, either way, unbridge.

- There's quite a bit of jittering and i'm using AdHoc
Try lowering the voice frames per packet, if your using AdHoc it appears you only have a lot less bandwith than when using an acesspoint.

- The signal strength isn't showing when I use the phone ad-hoc
This is a limitation of Ad-hoc, not of the phone, this is normal.

The new firmwares are a MASSIVE improvement (The Web GUI is actually starting to look pretty sexy). Don't bridge your connections though as you'll be upset and make sure you know your using a codec asterisk actually can use!

333It's junk

by Oinos, Friday 24 of March, 2006 [05:36:32 UTC]
Ordered one (P2000W_V2) for a customer who wanted a portable VoIP phone. It shipped with WV0002 firmware, but couldn't get it to register with customer's asterisk system or any of our test VoIP services. Uploaded firmware WV0003 (dated January 2006). After two hours of Erasing/Writing/Wait for reboot messages, phone turned off (it was plugged into the wall wart). Turning it back on, it wouldn't boot. It's pretty much a brick at this point and will be going back to the vendor. I can't say I'm all that anxious to get this replaced, I may just ask for a refund and tell the customer that he can't have Wifi VoIP.

333Not nice ...

by rszemeti, Sunday 05 of February, 2006 [03:07:17 UTC]
Lots of problems here ... battery life is very short (few hours at most), ships with v10 firmware, which is awful, plenty of problems even upgrading to new version (must use IE, must be on same subnet etc) in ad-hoc mode, connectivity is poor. call can be made, audio is bursty and distorted. whenever anything happens, phone processor seem to get busy, keypresses get missed, etc. Hardware wise, the phone does not seat correctly in its cradle, so you often go to pick it up and its gone flat. I have yet to make a succesful call, although I have atleast now got to the authenticating and dialling out stage .. its just the audio thats screwy now .. and hanging up onoce in progress is not happening either.

not one I would buy again, seems to be a bit of a dead duck

333Re: Roaming handoff

by mogmismo, Wednesday 11 of January, 2006 [16:13:46 UTC]
Here's the answer directly from Zyxcel, after a 3 week tech support back/forth:

<blockquote>
The implementation of the P2000Wv1 wireless association is that it will not associate to stronger access point RF coverage because it already has a connection to the original access
 point. The P2000Wv1 will not switch to the next AP until it cannot connect the original access point. This is related to the wireless issue you are experiencing. Using any WiFi phone over  
wireless you may notice the slightest loss of voice RTP packets since they are UDP.

The solution for this is to arrange the AP coverage with the least overlapping as possible or switch to the P2000Wv2 where you will notice less packet loss when switching to different AP’s.
</blockquote>

Hope this helps other people following, avoid the P2000Wv1 in a enterprise setting (Anywhere with more than 1 AP)

333Roaming handoff

by mogmismo, Monday 21 of November, 2005 [18:03:18 UTC]
Having trouble handing off between multiple AP's (proxim/orinioco ap-2000's). Signal-to-noise has to get to the single digits before it'll look for a new AP. All other devices on our network hand off just fine. We've tried with wj-00.a and wj00.10.

Any ideas?

Thanks,

M.

333DTMF

by Floppe, Sunday 27 of March, 2005 [14:14:44 UTC]
Hi,

I'm having problems with DTMF on the 2000W. Upgraded firmware to 0f and no change. It's like * doesn't read the tones att all. Can't login to voicemail or transfer calls etc.

333MWI now supported

by csekiya, Friday 25 of March, 2005 [04:08:58 UTC]
As of WJ.00.10 (which seems to only be available from the US download site), there is now an operational MWI on the display.

333Re: Does not reliably work

by , Wednesday 16 of February, 2005 [11:06:58 UTC]
I had this, and looking at the logs, it seemed to be ttrying to use g729a, even though
I'd configured both ends to use ulaw.
I bought a license g729a from Digium and configured it as the default, and the problem went away.
It also started working much better with 128bit WEP.
I still don't like the phone though.

333Works

Hi!

I'm been using a P2000W for a month now and for me it works quite ok. Nice sound quality.
But it has no MWI, and that's bad :)
