I'm looking for some help with a problem I'm experiencing linking an Option 11 with an Asterisk system. We currently have PRI service over a T1 with DID supplied by AT&T connecting our Nortel to the PSTN. The switch in the CO is a DMS100.
We are trying to insert an Asterisk-based system between the CO and the Nortel to do some IVR/VM/SIP stuff with. The Asterisk box has a dual-T1 interface in it. I setup all the configs on the Asterisk box so that port 0 would take the timing from the CO, emulate a DMS100, and act like the CPE in the link. Port 1 on that card then provides timing to it's link, emulates a DMS100 and acts like the NET side of the link.
Over the weekend, I disconnected the smartjack from the CSU and inserted the Asterisk system between. The T1 to the CO came up like a charm and I could route calls both directions from the Asterisk box and the PSTN.
The link between the Asterisk box and the Nortel also came up with no errors but when I try to route calls over the link, they are failing. When I try to route from the Nortel to the Asterisk box, I get a cause code of 100 on the Asterisk side and a debug message on the Nortel. When I try to call from the Asterisk side to the Nortel, I get a cause code of 54.
Calls coming from the CO arrive as a 4-digit DID. I sent the same 4-digit DID to the Nortel and it didn't work. I also tried 7-digit and 10-digit formats with no luck.
Has anybody seen these types of errors before? My gut tells me it is a Nortel thing because of the success getting calls (with the same basic config) in and out of the PSTN.
Any suggestions would be a big help.
Thanks!
Jason
