I do not have a instruction manual for my Avaya 4610. Where do I get one?

Sort of. You can set the .txtx file for the items that are currently in it. BUT, once the phone gets the file, all you need to do is put the extension number in, thne the personal info is grabbed from the callsrv IP, and the user information is automatically inserted,

You can logoff the current extension by hitting the options button, then the next page, then logoff.

Then you can re-logon as a new extension. Then enter the password.

Are both the gateway and the phone on the same group?

can you do a status station and give me a look at the screen shot

CS60 from Plantronics. A bit expensive but perfect

The software vpn probably will not work.
Is the vpn tunnel up? Can you ping the IPO? what subnet is the pc?
