Outgoing calls disconnected on answer / location of log files?

[phirephoto]

So multi part question. New user, migrated from an OLD version of freepbx/ trixbox, now running 3CX / PBXIAF. Great how easy it was to set up!
I have a generic sip phone - wifi cordless phone. Worked fine under Trixbox. But now with PBXIAF, when I make calls to certain numbers (no rhyme or reason but it's always the same number), as soon as the calling party answers, the phone disconnects. No idea what the calls it happens to have in common. Which leads me to the logs - where are the logs I should be looking at? The activity log for some reason now is blank, but I want to say it said "404" in the log?
I'm running PBXIAF on a laptop on my LAN, same LAN the cordless sip is on.
If I decide to go to a colo server, can I simply export my settings and then import into the colo machine? I mean basically I'd want my trunk setup, extensions, inbound rules, etc?

Thanks

So tried calling another number - according to the friend I called, his phone rang for about half a second, hung up, rang again for half a second, hung up, then rang so he could pick up. I heard about 5 seconds of silence before it rang (presumably while the ring / hang up happened).

Ok, tested again - the logs say

09/25/2018 8:02:01 PM - [CM503003]: Call(C:53): Call to <sip:00@IP:5060> has failed; Cause: 487 Request Terminated/INVITE from IP:50060 on these calls.

Anyone?

I'm just wondering about the invite from IP :50060 is that the intended port number? as apposed to :5060 ?

No, it's not.. I saw that too, not sure where it came from? I did a fresh reinstall of 3cx last night, and it seemed to work now, I'll do some more testing, but even before the reinstall I didn't see 50060 anywhere on the phone or 3cx...
