We have an Asterisk pbx between the PSTN and our old pbx. Lots and lots of details to get right, but just take your time and work through them. * Thing through your dialplan in advance. * Which number goes where. * How do you dial from one system to another. (This depends to a large degree on your existing pbx) * Most user prefer the dialplan at each pbx to be prefix-free (see http://en.wikipedia.org/wiki/Prefix-free_code) i.e. that you dont have both 345 and 3456 as valid extensions at the same time. * Get the details on the isdn signalling * How many digits and which numbering plan are incoming/ougoing called numbers and callerid delivered/expected. * Which signalling format (since you use BRI I expect it to be EuroISDN). * Get the timing right. * You will almost certainly accept timing from the PSTN and provide it to the other pbx. * Multi-bri cards can take the timing from the PSTN and provide an identical clock to the other pbx. This preevents bit-slips and is a good thing.
