Cisco IP Communicator troubles (Probably more than my current issue)

Back after so long… and I come before you all once again with everyone’s least favorite topic: Cisco-related anything…

I will preface by saying that if you feel the need to do anything that isn’t productive to resolving this, then just click off the topic, nobody said you HAD to reply if you don’t like it… At least this is the short-version of it… Also, my budget is $0 and less, so if you feel the need to suggest that I need to buy anything that YOU want everyone and their cat to have, again, click off the topic… Or buy it for me, I’d be happy to discuss requisitions done on my behalf. But joking aside, I’m just trying to get an absolute barebones “system” going with a single endpoint and nothing else, everything else I have to say on the matter is not the subject.

With that out of the way, I have an issue with getting Cisco’s (very long since EOL) softphone to register with FreePBX 16 on Asterisk 18.16.0, I used to just be stuck on a “Registering” loop, but I discovered my original install was locked to SCCP, which is not going to fly. So I grabbed an install from a different source, this one contained the actual .msi installer which I could launch from my Windows “terminal”, so got that on SIP, and as it turns out, I’m now stuck on “Unprovisioned”… and all my past experience that I brushed the dust off of turned out to not help (as it revolved around a 7941 and a 7965), so I come before you all requesting assistance on the matter (Of course, a simple “No” will work just fine, I guess…)

I am unsure which links are needed, so I will provide both pastebin and Google Drive links… The softphone obviously requires no firmware files, so no loads files or whatnot…

The cnf.xml file I originally used:

The cnf.xml file I am using now:

“That’s fine and dandy, dude, but skip to the end, what’s the end-goal?”
Think I already said what it was, but I’m just wanting a single-user system to just take a trip down memory lane some more and explore the feature codes I can use, just a barebones system, something I can use with a single unit until I get another job and some income so I can procure more phones (preferably Cisco, I know, so atrocious and illegal and all that… I don’t care…) and brush off the dust on my experience properly…

Again… if you HAVE to comment and are unwilling to help… a simple “No” will do just fine…

Perhaps I was in too much of a rush to write the original post… I now realize this after having had a night’s rest and some breakfast. Things I’ve tried is installing things that would normally be included with any Linux distro (primarily apt-get and all that, at least whatever the install would find without any hassle, in fact, that was mostly all that I could get really…) I’ve observed the Asterisk CLI for anything that might suggest any form of progress, but it all came up nil, in other words, Asterisk wouldn’t report anything while “sip set debug on” was true, so that tells me that the softphone wasn’t making any kind of attempt or effort to connect, which is worrisome… but I guess it’s still slight progress than getting stuck on any kind of “registering” error… and I verified that all the IPs in the settings and the config xml were correct, I’ve attempted pretty much everything that I could find on Google while making an effort to prevent their AI from butting in… at least whatever seemed closest to my situation, though of course Cisco is very much frowned upon by a great many of people here… I feel unreasonably so, but then again, that’s just my opinion, which doesn’t really matter… Anyway, I’ve swapped between PJSIP and Legacy SIP while adjusting the config for the softphone, so I’m really putting in the effort here… I get that Cisco-related anything is, I guess what most people here would consider “taboo” or “unsavory” or whatever y’all say… but keep in mind, my autistic brain is attracted to these phones, they’ve been around for ages, I grew up with these phones since Elementary school, but again, details that mean jack… If it’s a challenge, that’s one I’m willing to take on, but obviously assistance will be needed where appropriate, I’m sure once I have physical phones again, my experience from 2020 or so can really shine, and you won’t get me asking how to set them up again, because it’ll just come naturally…
