Hi Guys, Have just upgraded one of our PSTN gateways from an old as5300 to a new as5350xm. Have run into an issue whereby incoming calls from PSTN which have callerID blocked won't complete, and just seem to get dropped on the floor. I get the following debug output when I make a call from callerid blocked number to the gateway - seems odd because the only references I can find to this error message are for outgoing calls.. Of note is the Plan / type which are Unknown, and the drop cause. Cause i = 0x809C - Invalid number format (incomplete number) 00124: Aug 26 19:24:54.621 NZST: ISDN Se3/0:15 Q931: RX <- SETUP pd = 8 callref = 0x01FF Sending Complete Bearer Capability i = 0x9090A3 Standard = CCITT Transfer Capability = 3.1kHz Audio Transfer Mode = Circuit Transfer Rate = 64 kbit/s Channel ID i = 0xA18381 Preferred, Channel 1 Progress Ind i = 0x8283 - Origination address is non-ISDN Date/Time i = 0x0A081A1318 Date (dd-mm-yr) = 10-08-26 Time (hr:mnt:sec) = 19:24:52 Signal i = 0x40 - Alerting on - pattern 0 Calling Party Number i = 0x00A3, N/A Plan:Unknown, Type:Unknown Called Party Number i = 0x80, '4987770' Plan:Unknown, Type:Unknown 000125: Aug 26 19:24:54.621 NZST: ISDN Se3/0:15 Q931: Received SETUP callref = 0x81FF callID = 0x0017 switch = primary-net5 interface = User 000126: Aug 26 19:24:54.621 NZST: ISDN Se3/0:15 Q931: TX -> RELEASE_COMP pd = 8 callref = 0x81FF Cause i = 0x809C - Invalid number format (incomplete number) 000127: Aug 26 19:25:04.058 NZST: %CALLTRKR-6-CALL_RECORD: ct_hndl=25, service=None, origin=Answer, category=SyncData, DS0 slot/port/ds1/chan=3/0/0/0, called=4987770, calling=(n/a), resource slot/port=(n/a)/(n/a), userid=(n/a), ip=0.0.0.0, account id=(n/a), setup=08/26/2010 19:24:53, conn=0.00, phys=0.00, service=0.00, authen=0.00, init-rx/tx b-rate=0/0, rx/tx chars=0/0, charged units=0, time=0.01, disc subsys=ISDN, disc code=0x1C, disc text=Invalid number format (incomplete number), sig type=Unknwn Anyone run into this kind of thing before and have any ideas how I might configure the box so that these calls complete?
