Incoming calls do not ring long enough

Use feature 986 (transfer to VM) then enter in the co-workers extension number. That will bypass the extension and send the caller directly to his voicemail.

You may have turned the radio off on your phone by activating Airplane mode. This mode will send all calls to your voice mail.

Check your owners manual to re-active your phone to Normal mode.

When you say voice mail, do you mean your personal vmail box or the AutoAttendant? If so you'll need to login to the 998 mailbox and modify the "Custom Service" prompts (menu# 5-3). NOw as far as the ringing goes, you might try doing an extension data clear procedure by doing Intercom -> *790 (I think it's Intercom 7900 on the older systems). Otherwise you should call a local Panasonic Dealer for a service call. Contact me offline for a referral.

This can be handled by the DND feature in your admin settings... Do not disturb will transfer your calls direct to voicemail without ringing the handset.

might be any software trouble check with service centre

I think I would get a different phone.

Is the caller being transfered to the ext or is it on incoming calls?

if you have voice mail, you can set the number of rings before forwarding to voice mail in the administrative options of the voice mail menu itself. Call your voicemail and listen for administrative options. Follow the prompts.

get your mailbox number then type in **61*44then mailbox mumber*11*then a two digit number between 00 and 30 (seconds delay).

Typically you want your phone system to ring your phones (say extension 10, 11 and 15) and then if no one answers after so many rings the call is transfered to the port the voice mail is on (let's say it's port 16) The voice mail is set to answer right away but does not "ring" until the call is transfered to it. This way (at 4 rings) if a call comes in on line 1 and you answer after 3 rings but a call comes in on line 2 at the same time, the first ring on line 2 will not make the total = 4 and set off the voice mail. I would guess the port at your voice mail is not set to ring and nothing is set up to transfer calls to your voice mail. Did you set this up yourself? How did you program the phone system?
