Hi all, We we send a server out to a customer with a PRI card I basically tell the PBX person that we want national, NI2, b8zs, D channel is on 24, and we are the CPE and your the NET and us a cross over cable. Allow extensions, local calls and long distance. on the surface I would have thought this would be enough for them to connect the digium card to the PBX and get calls working. The PBX guy "seems" to always complain about how he has MANY options and thats not enough information... What else am I supposed to supply this person. Are they not the PBX expert?... Anyway as example. the last customer I told the above information. He set up the PBX and I can make 4 digit calls successfully, 7 digit and long distance are not successful. They are hitting some error condition that the call is going to the switch board. So the connection is working just not completely working. This is connecting to a nortel 1000 pbx. I dont know anything about a nortel switch to them what to change. What should I be supplying to these PBX guys to get the installs going smoother and quicker? Jerry

Either the PBX or asterisk needs to compensate so that calls play nice with each other * when in doubt, get a local shell on the box and then tell the people what you changed

Nortel has what is called BARS/NARS. The ability to dial numbers to access certain routes is based on the Network Class of Service (NCOS) of a telephone or trunk. I would suspect that the user has the trunk set with a NCOS to low to access the outbound routes. Also, tandem calls from the Tie line to the outside trunks will need to dial the proper access code to activate BARS/NARS. (Ie. If a Nortel user needs to dial 9, so does the call from the tie trunk.) There is also the option, instead of using the BARS/NARS access code, the tie can use the route access code (ACOD) directly. As far as the PRI setup, I have found that I prefer QSIG (if the Nortel system release supports it) because if will properly pass all the CLID info between systems, NI2 did not. I hope this helps.
