Hi All
Sorry for my late answer, i was busy resolving various issues.
I did not resolve this matter yet, but i found out the problem. Yes the UC360 is updated to latest version since the first time.
The SIP service of the MCD is down! The MCD was upgraded recently by another Mitel partner, not me, and propably there were some errors during the installation.
The funny and hard part is, that i have to reinstall software again.
If you are wondering how i found out that sip service is down, first of all with port scanning no responce from system on port 5060, and second when issuing maintenance command SIP REGISTAR CONFIG, the system replies cannot print output, check software logs. On software logs it says SIP_AUX task has not yet started. Interesting isn't it?
