Yes, thats how a M2W works. Great for W/H phones, Any digital or slt w/ electronic ringer. At site of phone connect input to speaker leads, mount the little volume control and the speaker.
When phone not in use, rings via speaker. Phone used as normal except no monitor or speakerphone use. Pretty obvious to end user, if you go to phone and hit speaker, you get ICM tone over speaker, pickup handset and works as normal.
If speaker provides subdued OFF HOOK RING, you will get that too.
Sometimes the best way to get Page, All Page and flexible ringing to an area that is programable through switch.
