You have 2 options here for the (XXX) section. Option 1 is to see if
your panasonic pbx supports a T1 interface, and is afordable for the
number of lines you wish to connect via asterisk. Or you use a FXO/FXS
solution to connect the 2. Since it is easier to get FXO ports for
asterisk right now than FXS ports, you will want to connect a FXS port
of the panasonic pbx to a FXO port on the asterisk machine. So you
probably want to get X100P cards in the number of lines you wish to be
able to connect to the far side.

I am hoping to implement an asterisk system between two offices as below

|-------|
| PBX   |-----(XXX)--[asterisk]---[VPN]----[asterisk]--(FXO)--phone
|-------|                                         |
                                                   |-(FXS)--PSTN

I am unsure which interface I need to connect the existing analog 
(Panasonic) PBX to asterisk, assuming  I will be connecting on the 
office side of the PBX (making the asterisk an extension on the PBX).

I am assuming it will be an FXO and envisage using Zaptel interfaces. 
Replacing the PBX with asterisk is not an option at this stage.

As I am in New Zealand, which uses different ring tones/cadences to the 
US, are there any issues there?

Any comments, caveats on this setup gratefully received.

Richard Scobie

I have done exactly taht usingdigium x100p cards... :)

Very nice indeed...

Thanks for the reply Steven.

I was hoping to connect to the FXO side of the PBX, as this would allow 
people in the PBX office to call  the remote office, using an internal 
extension number. At the remote office end, a user can dial a PBX office 
extension directly and also make PBX office local PSTN calls by dialling 
the PBX outside line prefix.

I had been thinking of using the S100U FXS to do the above, but going by 
your comment, would I be better waiting for the TDM10B to become available.

Perhaps I can do all this from the FXS side of the PBX - currently I am 
still learning the capabilities of the Panasonic.
