so i installed an external paging amplifier (university sound 1100-10) and two VTF-152UCN
Voice/Tone™ Recessed Compression Driver Loudspeaker 25V 15W to the system using the 2 ext paging ports on the TDE200. I have been able to assign a floating extension number to each port (655 & 656), but it only sends a tone, no ability to speak and unable to get the pt extensions (208 & 217) to ring the loudspeakers.... what have i overlooked?

Thanks for all your help!
