Hi, all I have been asked if it will be possible to conenct Asterisk to a commercial PABX. Company has an established call center, but want to use Asterisk for long distance inter-office calls and they want to use existing phone system. At the moment all I know is that they have Siemens PBX system. They will give me more details soon. Since I never tried that before, I want to get some information before I even talk to them. Did anyone try to connect to an office PBX? What interfaces PBX typically expose? What to look out for? Any links will be greatly appreciated. Thanks, Rudolf
The 2 options are ISDN (go ETSI if you can) or analogue lines. I know Jurgen hooked up his Asterisk Box to his old PABX via Analogue lines.

Hi Rudolf, Paul's right, I've configured our Asterisk box to talk to our existing (and on its way out the door) analogue PABX. It's a bit of a hacky kludge, but I'm using an analogue 4-port FXO card in the Asterisk box, connected to four analogue extensions out of the old PABX. I could also have used an FXS card and configured the old PABX to recognise them as 4 ordinary PSTN trunks, but when the system goes live, I wouldn't need any FXS ports, so I didn't bother. Trunking is probably the more "correct" solution here though. If you need more than 4 concurrent lines, and have the capability, take a look at trunking them together with ISDN. This is a bit beyond what I've tried here, but it ought to work. ......jurgen On Thu, 31 Mar 2005 09:03:21 +1000, rudolfl@optusnet.com.au <rudolfl@optusnet.com.au> wrote:> Hi, all > > I have been asked if it will be possible to conenct Asterisk to a commercial PABX. > > Company has an established call center, but want to use Asterisk for long distance > inter-office calls and they want to use existing phone system. > At the moment all I know is that they have Siemens PBX system.

Stay away from analogue links since they will introduce two additional hybrids (2- to 4-wire conversions) and the signalling is still not very precise. We have hooked up our Panasonic to Asterisk with an E1 PRI. Peter
