Hey,
Am using a cucm 8.5 and i have deployed different sets of phones
they are working correctly, ringing instantly when you initiate a call to another phone
But when i initiate a call or transfer from the DX650 phones to another phone like 7875 or 7911 etc..
It takes more second before the calls goes through
Whereas other phones calling the DX650 it rings instantly.
I don't when if that's how it is or is a system default way
