Innomedia has 24 port MTAs with amphenol connections.  We use them quite a bit

Honestly just for signaling efficiency. I do everything with TLS, and maintaining 900+ TLS sessions all the time is wasteful, especially for endpoints that will be infrequently used. I would prefer to register a single signaling trunk per device.

When I read your email the first thought that popped into my head was a bunch of Calix E5-111s used for pennies on the dollar. They are simply ADSL/POTs boxes. 48 ports of pots. But each line registers individually. But at least the box is stupid dumb and you handle everything on the switch side. I would not want anything complex on site barring a distinct requirement. Of course just turn off the ADSL.
Why do you prefer that the lines do not register individually? Do you have a requirement for so much box intelligence in their closets?

I have found myself with a number of hospital opportunities and 
 servicing the staff with IP phones is a no-brainer, however there is the 
 need for multi-hundred room connectivity for patient room phones and the 
 staff mandate is to keep it analog because "ip phones there will grow 

 I am looking for 24+ port density with amphenol connectors, and ideally 
 some kind of rudimentary internal routing so i dont need to register all 
 24 discreet ports and can route by some header (to or uri) within a 
 single registration.

 Right now im looking at AudioCodes and the Sangoma Vega series. Obihai 
 would be my natural choice here but don't have anything that fits my 
 density requirements.

 Any opinions on these or others I should consider. Anyone deploy these 
 and can speak to the experience?

 Thanks in advance
