NEC DT800 STD SIP Firmware

[gyrow]

As many others, I'm trying to connect my DT800 to an asterisk PBX, so I think I need the std sip firmware for the dt800?

hw version: 9.1.61. (type A)
fw version: 4.0.2.0
terminal type: ITZ-12DG-**TEL

Thank you

As I keep trying to point out to those who come here for this, yes someone here can supply it (try the search feature and you will find it) but it isn't worth the effort. First once you have it you then need to load it (not that easy) and then you end up with a really dumb phone that you can't even program any keys on. The phone ends up dumber than most analogue phones from the last 3 decades!

It was 3 am when I posted this thread, I saw other people posting and I didn't see your comment anywhere nor I didn't find any that was still open with the limited brain power left after hacking at this for 5 hours.
At the moment, I don't own a NEC PBX (and I never will), and thus the phone does absolutely nothing but spew the "SIP Server Not Found" message, along side some packets in Wireshark showing it does do the register, 401, register, 200 flow. If you have a different suggestion on how to make the phone useful, I'm happy to accept that answer. Otherwise I will have to settle for a dumb VoIP phone that can call other phones on the network (which is all that I want to use it for to be honest).

Look for posts by Belvedere, he regularly helps with this.

Thanks to everyone who share the dropbox link with me.
So if I get it correctly, I need the itzisipvg.tgz but I cannot find it in any of the folders. Is there a specific file I should be using instead?

There are no files in the usual std sip firmware that start with itz.

From your first post what do the ** represent? that is important as there are a few NEC phones that cannot be converted to STD SIP.

terminal type: ITZ-12DG-**TEL

Looking over my old documents I see that at least in 2016 the only model of DT800 series phones that is compatible with the NEC 3C system (standard sip) is the DT820. All other DT800 series phones were not supported. This is may still be the same today as every version of standard sip I ever downloaded from NEC only supported the DT820 phone.
