I have problem with hold ring

mY dear Your Phone Ringer Default So Please change Ringer
And Ringing Sound Problem will solved

You don't. Panasonic analog system phones have one ring tone. You can change the cadence (single double or triple) ring from outside calls, but not the tone.

Try pressing Intercom then 7311 and 7321. You may have to hit the pound key after each one.

I think it can be done. Just exchange the phone for a 7633 and change out the TA for a TDA-50.

Piece of cake.

Your phone will work on a few different Panasonic phone systems. If you are looking for manuals on KX-T7720 and KX-T7720 all you will find is a user guide for the phone. You need to determine the model number of your phone system before starting to look for a programming manual.
