Using UCM6202 with just 6 extensions in use (although ive created more). Each ext has a GXP1620 on the end but im finding that the management portal is showing some of the extensions as ‘unavailable’.
For instance, i have put the UCM as extension 1 (don’t know if this is right or not)
And currently Its showing as offline although its functioning ok.
2 of the other 5 physical phones are showing offline too.
Any ideas why this is happening?
