[VoiceOps] Centrex Nodes

[Nathan Anderson]

It occurs to me that if you didn't want to build an Asterisk box with a PRI interface, or hunt down an already-assembled embedded system that can run Asterisk and has a built-in T1/PRI interface (they are scarce) and wanted an off-the-shelf solution instead, you could probably pair the Citel Portico box up with an Adtran TA900e.  Phones go into Citel, Citel talks SIP with Adtran, Adtran terminates telco PRI.

Read the product description again.  This piece of equipment services digital Centrex phones (Nortel DMS/"P phone").  It doesn't have the PRI interface, but that is easily fixed with an Asterisk or Freeswitch box wth a T1/PRI card in it.  Connect the Citel Portico-TVA up to the Asterisk box via Ethernet and have them peer with each other with SIP.  Problem solved.

I'm actually looking for a piece of equipment to do the opposite. Service digital Centrex phones but accept a PRI input without the huge DMS switch.

You didn't specify analog or digital Centrex but I assume digital because as far as I know, all analog "Centrex" phones use the same signalling as any analog phone (i.e., loop start + DTMF + FSK-modulated CID).

(A second quick Google suggests the above product is actually called the Portico: http://www.citel.com/products/portico-tva/)

Hey,

Does anyone know of any remote nodes or mini PBX that can run Centrex phones but essential connect to a PRI?

Thanks,
