I have a few Inter-Tel 8662 (FW ver 2.2.02) phones laying around and a Mitel 5000 (5.0.4.75) with 5 unused category "C" licenses. It's my understanding that the "C" license allows 8662s in SIP mode, but I can't seem to figure out how to get it to work. I've tried creating both 86xx and SIP extensions, but I get licensing errors on both. I get a licensing error trying to use an 86xx extension with the 8662 in ITP mode because I don't have "A" licenses. That makes sense. However, I also get a licensing error when the phone is in SIP mode trying to use a SIP extension on the 5000. I've even tried the phone in SIP mode with a 86xx extension on the 5000, but I don't see how that would work at all.
Has anyone here ever used a "C" license this way or have any suggestions on what I might be missing? Below is what the documentation reads on the category "C" license.
