How do you create a 3rd-party SIP line? I just obtained end-point licenses for this type of line.

What command(s) to use to build a line?

If you are referring SIP line as in SIP trunk, then star at 10-40-01, 10-40-02 ...

Oops my bad, my command is for SV8100 !

You are correct: I have an sv8500. And I'm trying to make a SIP phone working, not a SIP trunk.

Per the manual, you use ASPO and ASPTN (and possibly ASPW to create a registration password). What happens is this:
ASPO only takes a max 5-digit extension, yet all my extensions are 6-digit. So I don't even know how to start. Still, I tried. I put in a bogus 5-digit extension and then went to ASPTN, where I "mapped" (if you will) that 5-digit extension to a desired new 6-digit extension.
But my SIP phone won't register with the phone system. It keeps getting a 403 error message which has something to do with rejected registration attempt. I tried not defining a registration password in ASPW but got the same message.
I do have 3rd party SIP licenses.
Anybody has any idea?

Here is a follow-up:
I was finally able to make a softphone, XLite working. Looks like it has some setting that I didn't managed to identify in the other ones and set correctly first. Then I played around with another softphone, and bam! I got that one working. It appears that you have to put in the actual SV8500 SIP server side domain name somewhere in the softphone config, and the username has to be "user". That seems to do the trick so far. Now I have to start playing with some hard-phones. There is still an issue with the softphones though. I can only call sta-to-sta. Outside calls get rejected with "unsupported media" error.
