Location: Missouri Rep Power: 6  | Routing problem involving SPN and NRS Just installed signalling servers on two switches and upgraded from IPT 2.x to IP Line using H.323 trunks. Conversion was a nightmare and won't go into it, but am having some strange issue with one SPN. Trying to send all toll-free (800, 888, 877, etc.) down the IP trunks; all of these EXCEPT 1800 calls are working. SPNs are the same and both send to the same RLI. However, for whatever reason, the calls are getting marked as a different num plan, and I don't know why. I have an entry in the NRS for "18" marking the calls as "Private Special". Any ideas? (note that this did work before under IPT 2.x). Failing call: DCH 20 OMSG SETUP REF 000001A0 CH 97 0 0 31 TOD 16:42:26 FEAT :NCID PROGRESS: ORIG ADDR IS NOT ISDN CALLING #:NPANXX1234 NUM PLAN: E164/NATIONAL / NPA CALLED #:1800NXX1234 NUM PLAN: E164/NATIONAL / NPA DCH 20 IMSG CALLPROC REF 000001A0 CH 97 0 0 31 TOD 16:42:26 DCH 20 IMSG DISC REF 000001A0 CH 97 0 0 31 TOD 16:42:26 CAUSE :NO CHANNEL/CIRC AVAIL DCH 20 OMSG RELEASE REF 000001A0 CH 97 0 0 31 TOD 16:42:26 Good call: DCH 20 OMSG SETUP REF 000001A0 CH 97 0 0 31 TOD 16:42:02 FEAT :NCID PROGRESS: ORIG ADDR IS NOT ISDN CALLING #:1234 NUM PLAN: PRIVATE/UNKNOWN (UNKNOWN) CALLED #:1888NXX4321 NUM PLAN: PRIVATE/NETWORK SPECIFIC (SPN) DCH 20 IMSG CALLPROC REF 000001A0 CH 97 0 0 31 TOD 16:42:02 DCH 20 IMSG PROGRESS REF 000001A0 CH 97 0 0 31 TOD 16:42:06 FEAT :NCID PROGRESS: CALL IS NOT END TO END ISDN | ||||||||

| Junior Member | NRS never marks any calls. NRS is routing calls according prefix and type of number. If you define in NRS that some site have prefix "18" with type of number Private Special, then NRS will route call to that site only with appropriate digits and type. You can make another entry in NRS for "18" with E.164 National type of number so it will allow routing of this numbers to defined node. It calls "type of number routing". |

Location: Missouri Rep Power: 6 | Ok, so that fixed the issue; thanks for the pointer. Upon further review I just found in the NTPs that Nortel treats an SPN of 1800 as a national number in certain instances, according to the LD 90 description of the INPL prompt. Guess they never thought of 1888m 1877, etc. | ||||||||
