Hitachi WiFi VoIP up and running!

Finally got my cheap-from-ebay Hitachi WirelessIP 5000 phone working. Took a lot of doing:
Seems to have semi-poor wireless reception, worse than my not-great aluminum powerbook. Audio quality is still in progress, not sure I have it setup right. I’m getting a lot of these from Asterisk:
-- Got SIP response 606 "Not Acceptable" back from 204.128.136.100
No help from google, surprisingly.
Since the manuals were hard to find, I’m mirroring them locally for anyone else who needs them:
WIP-5000_WebInterface.pdf
WirelessIP5000_SE_Manual_jul.pdf
WirelessIP5000_Users_manual_jul.pdf
We’ll see how this goes. I really, really love the idea of unlimited phone calls for twenty bucks a month. In other words, email me if you want to talk and I’ll send you the new VoIP number.
Update 11/23/06:
I still get 606 errors, but I have new firmware I need to try. The wiki page on this phone has some ideas, so maybe when I get home I’ll try a firmware update. I’m also considering just selling it and switching to a Nokia N80, which has SIP/Asterisk support.
Update 12/20/06:
Sold it on Ebay and bought a Sipura 3012 FXS/FXO adapter. Too much hassle with the Hitachi.

We have 36 Hitachi WIP 5000 and constantly get “Got SIP response 606 “Not Acceptable” back from” messages. Has anyone figured this one out yet?

I also get the 606 errors but only when the mailbox= line is set in sip.conf. If I turn on sip debug, I see the response is from the voicemail notification messages. I thought this phone was supposed to support MWI?

I appear to have fixed the 606 errors. MWI had to be turned on. Logged in to the web server as admin and under configuration->MWI, turned on MWI and the error went away for me.

[...] I had a fair bit of grief with my Hitachi phone and finally eBay’d it off. In its place is the Sipura 3102, a 3-interface device of considerable sophistication. It has FXS, FXO, WAN and LAN ports, meaning that it is: [...]
