Look at the chips used in common ATA I like the PAP2T from Linksys (now Cisco) .
It's just like any other interface use the off hook and ring or reverse battery like your E&M On the "Trigger Base" you could configure the ATA for "hot dial" where it would connect upon off hook. Hope this helps Robert.

Granted, I am casting a rather wide net here on a fact finding mission to see if the group is aware of any other brands that I had not covered. As for pricing, we will be dealing at OEM level, so its a volume issue as well as features and performance. In NZ we refer to a trigger base as a semi duplex radio (On Mobile Frequencies) that is mounted at a fixed location. Often these are line controlled via E&M, or in our instances ROIP. Hope this helps?

And what features are you specifically looking for them to have? BTW, what is a 'trigger base'? A control station?
