I have in a lab environment a UC520 with 4 phones. 7941, 7940, 7911, 7905.
I have issues with the 7941. it has registered fine but when I pick the handset up I get no dial tone, the other phones are fine. When I call the other phones from the 7941 they ring, pick up the handset and there is no communication either way. Communications between the 7940, 7911 & 7905 seems fine.
Any help to get this issue resolved will be greatly appreciated.
Ok ... dopey question here, but is the handset plugged into the handset port or the headset port?
Otherwise swap a handset off one of the other phones and see if there is something wrong with it.
For the incorrect time on the 7941, you need to go under telephony-service and add the command 'time-zone ' that corresponds to the local timezone. Once this is done, do 'no create cnf-file' and 'create-cnf' to rebuild the XML config files and 'reset all' the phones. The time should be correct on the phones after the reload.
