Hi All, Sorry for the double post, but I'm in a real bind. I have several * servers connected to T1 PRI's from various service providers in multiple locations the US. All the * servers use the same hardware with the same OS and * version CVS-v1-0-11/09/04-12:27:27. When connected to 5ESS Switches, using the NI2 (national) PRI protocol, the CID name and number come across fine and populate into the * CDR fine. I connected to a DMS-500, NI2 (national) protocol and the CID name doesn't get populated in the * CDR. The only variance in the PRI debug outputs is this, from Asterisk debug when connected to the DMS switch: Jun 9 16:41:15 WARNING[30369]: chan_zap.c:7133 zt_pri_error: PRI: !! Facility message shorter than 14 bytes Facility (len=12, codeset=0) [ 0x9f, 0x8b, 0x01, 0x00, 0xa1, 0x01, 'H', 0x02, 0x01, 0x02 ] Can someone explain what len=12 means? On all the good results from the other switches, the len=23 or greater. The interesting part is that the CID name does come into the * server and is forwarded to the destination phone, the CID name and number does come across from the service provider. I'm thinking there is something particular with this DMS-500 causing this. Is there a special terminating setting I can throw into Zapata.conf to compensate for this short facility error? I was able to test with another DMS-500 with no problems, so I don't think it's a Nortel issue, I believe it to be a configuration problem on the serving switch PRI or possibly farther upstream in how they are gleaning the CID info from the SS7 stream. I can send full debug outputs from both working and non-working servers if needed. Any help would be greatly appreciated. Thanks in advance. JR
