If your the kind of person that can wire and "tweak" things here is my suggestion. Open the phone an run a pair of wires off of the wires going from the circuit board in the phone to the little speaker inside the phone. and run those to an amplifier and hook up speakers

How to use the paging sytem? KX-7633

So what happens when you dial *3301 on the intercom? It's not magic, but each phone by default is in page group 1. The external pager has to be assigned to it, so if it does not work, it's time to call your dealer/installer/engineer.

How to use the intercome? and Paging system?

How so? The TDA/TDE systems have page groups and external page is assigned to one of those groups at installation.
At the very minimum, you should be able to dial *3301-33xx on the intercom and page the different phones and external page assigned to that group. IIRC by default, system phones are usually in group 01. In passing, I think *43 from any phone will answer said page and cut off the speakers.

As far as the intercom, each phone is numbered and the extensions usually start a 101. You dial and it either rings or tones (that can be programmed) and you can use the intercom.

Somewhere, there is a user's guide (UG) for the phones. It's particular to the phone system, but the TDA book is universal for all systems. If you need it, comment back with your system model and I'll drop a link to you.

Press an intercom button and dial the 2 digit extension number. This will ring the extension. To page the extension, press an intercom button and then * (Star) and the 2 digit extension number. This will page the phone.

How do you page with a Meridian Norstar M7208 phone?

There is another page, acting more like a directed intercom page...

If you want to talk to someone and you know where they are (general area) you can do a FEATURE 6 6 and the extension number.

This is a direct page and when you page this way, that person can respond back and you can hear them.

Be sure you are pressing the correct extension key for the phone you are attempting to call. Just press 'intercom' and the key number (from the right side of the phone marked 1-16).
