we are using a UCM6208 (newest FW) and about 30 GXP2160.
Now i’ve bought some GXP1610 (also newest FW installed) Phones too. These are very laggy or sluggish. Hard to describe.
If i call this new extension it rings 5-7 seconds later. Also if i press the round middle button to see the State Screen it is slowly and i have to wait up to 3-4 seconds until the display is changing.
do you have any ideas what could be the reason?
-network config over dhcp
-the SIP Account is setted by UCM Zero config
-no other settings changed after factory reset
i’ve also tryed a other device GXP1610 , cable and switch port
