PRI to PRI Calls Fail - Intercept to Operator 1

[hskrdean]

I am working on connecting a faxing server to our CS1000 via a PRI T1 using NI2 d-channel. The T1 is up and connected and I can forward/send calls to the fax server through my incoming T1s, both local and LD (local DID and 800 #).

However, I cannot get any calls from the fax server to get out of the Nortel. Local/LD calls are intercepted and sent to the system operator. If the fax server dials a four digit extension, the call connects to the extension.

I have checked TARG/TGAR, NCOS/FRL and CLS. If a call goes one way through the system PRI to PRI, why won't it let it go through the other way?

LD 49 - Prt NCOS 0 (This is also affect your FRL in RDB



Villareal

 

[hskrdean]

Villareal- LD 49 is for the IDC table. NCOS 0 has an FRL of 0 as shown above in the LD 87 NCTL print out.

 

[johnpoole]

if your using ac1 or ac2 you bypass ld 49.. if your not using ld 90, good luck

Ok, so let me try to talk this through. The Fax server gets dial tone on the trunk to the PBX, then sends 9 +1 and the number. So I am using BARS to route the call to the LD trunks. But after the digits are sent, the call is intercepted and goes to the receptionist. I can see that by running a d-channel monitor trace.

I tried sending the call out a COT route, a PRI using TIE trunks and then changing it to use DID trunks. In all cases, the fax server call was intercepted.

I've got to be doing SOMETHING wrong, but I can't see it. ARGH!!!!

 

[yyrkroon]

Sounds like you're tandeming the call out, is this correct?

FaxServ - PRI - PBX - PRI - PSTN

If so, you need to insert a 9 into your outpulsed string from the fax server, that way you have access BARS on the PBX

Here's a copy of the d-channel trace from the fax server dch...

Tandem NI2 calls just don't work in Nortel. NI2 only allows for COT or DID type trunks. In order for the nortel to process your request, you'll have to build TIE trunks and NI2 doesn't support TIE.

Solution: Use QSIG TIEs or change to DTI E&M WNK TIE trunks.

Nortel doesn't function well as an NI2 traffic cop.
