Before I shell out for one of these, could the collected wisdom confirm or deny whether this is likely to work?

I want to connect a Patton 4554 to one of the outbound ISDN trunk lines on our existing PABX. All the words I've read about the Patton have it functioning as a terminal with an ISDN line coming from the outside world plugged into it; I want to replace one of our existing real ISDN lines with the Patton so that we can call out using a SIP provider instead.

Is this possible using the patton or do I need to look at something else?

Thanks, Neil.

You want to connect your ISDN phones to an IP PBX, right?

If I understood correctly what you would like to do I can tell you there are other products on the Patton website that can connect ISDN phones to an IP PBX, like this one: http://www.patton.com/products/pe_produ ... f9e261e449

There are various products, depending on how many BRIs you need.

The 4554 is meant to connect an IP PBX to the PSTN

Patton 4554
the 4554 does not have the option to switch the BRI from TE to NT.

Patton 463x
this option is available on the 4634 which has 3 BRI ports, but attention it can only handle 4 calls at one time, this should be enough if you will have one external and one internal BRI

Patton 4552
you should look for the 4552, this small unit has one external BRI an one connection called PHONE, there is no description one the patton website, you may find some information on the german www ebertlang de
http://www.telefonie-via-ip.de/0203-gateways.cfm#isdn
but cannot check if this phone connector is a real BRI port, we are getting one of this devices next week.
