[asterisk-users] No D-channels available! Using Primary channel 16 as D-channel anyway!
Dear Gurus, i am facing some unknown problem here.. first, let me describe my case. my office is using a nortel merridian option 11c PBX. and it is connected to the provider thru a E1 card, which is working fine with no problem. my plan it to slot in a server with 2 TE11XP card to intercept the outgoing calls. Provider --te11xp--- asterisk ---te11xp-- nortel merridian option 11c i had my asterisk set up with these configuration. zaptel.conf --- loadzone=uk defaultzone=uk span=1,1,1,ccs,hdb3,crc4,yellow span=2,0,1,ccs,hdb3,crc4,yellow bchan=1-15,32-46 dchan=16,47 bchan=17-31,48-62 --- where span 1 is to the provider and span 2 is to the PBX zapata.conf - context=from-pstn switchtype=dms100 signalling=pri_cpe callerid=asreceived group=1 callgroup=1 pickupgroup=1 rxgain=0.0 txgain=0.0 channel=1-15,17-31 context=from-pstn switchtype=dms100 signalling=pri_cpe callerid=asreceived group=2 callgroup=2 pickupgroup=2 rxgain=0.0 txgain=0.0 channel=32-46,48-62 able to start asterisk. Span 2 loaded beautifully, no problem or errors, but i get this WARNING[13655]: chan_zap.c:2287 pri_find_dchan: No D-channels available! Using Primary channel 16 as D-channel anyway! warning message from span 1. which i have no idea what happened.. the funny part is, i am able to receive calls, no problem at all. CID and DID are pass thru (for incoming). but when i try to make a outgoing calls, i got errors PRI HANGUP CAUSE 1 from the provider. i did a pri debug span 1 for the call i dialed, below are the msg. - -- Accepting call from '124' to '42707898' on channel 0/21, span 2 -- Executing Set(Zap/52-1, CALLERID(number)=50399100) in new stack -- Executing NoOp(Zap/52-1, 50399100) in new stack -- Executing Dial(Zap/52-1, ZAP/g0/42707898||) in new stack -- Making new call for cr 32771 -- Requested transfer capability: 0x00 - SPEECH Protocol Discriminator: Q.931 (8) len=39 Call Ref: len= 2 (reference 3/0x3) (Originator) Message type: SETUP (5) [04 03 80 90 a3] Bearer Capability (len= 5) [ Ext: 1 Q.931 Std: 0 Info transfer capability: Speech (0) Ext: 1 Trans mode/rate: 64kbps, circuit-mode (16) Ext: 1 User information layer 1: A-Law (35) [18 03 a9 83 81] Channel ID (len= 5) [ Ext: 1 IntID: Implicit, PRI Spare: 0, Exclusive Dchan: 0 ChanSel: Reserved Ext: 1 Coding: 0 Number Specified Channel Type: 3 Ext: 1 Channel: 1 ] [6c 0a 21 80 35 30 33 39 39 31 30 30] Calling Number (len=12) [ Ext: 0 TON: National Number (2) NPI: ISDN/Telephony Numbering Plan (E.164/E.163) (1) Presentation: Presentation permitted, user number not screened (0) '50399100' ] [70 09 a1 34 32 37 30 37 38 39 38] Called Number (len=11) [ Ext: 1 TON: National Number (2) NPI: ISDN/Telephony Numbering Plan (E.164/E.163) (1) '42707898' ] [a1]w*CLI Sending Complete (len= 1) -- Called g0/42707898 Protocol Discriminator: Q.931 (8) len=10 Call Ref: len= 2 (reference 3/0x3) (Terminator) Message type: CALL PROCEEDING (2) [18 03 a9 83 81] Channel ID (len= 5) [ Ext: 1 IntID: Implicit, PRI Spare: 0, Exclusive Dchan: 0 ChanSel: Reserved Ext: 1 Coding: 0 Number Specified Channel Type: 3 Ext: 1 Channel: 1 ] -- Processing IE 24 (cs0, Channel Identification) -- Zap/1-1 is proceeding passing it to Zap/52-1 Protocol Discriminator: Q.931 (8) len=17 Call Ref: len= 2 (reference 3/0x3) (Terminator) Message type: PROGRESS (3) [08 02 82 81] Cause (len= 4) [ Ext: 1 Coding: CCITT (ITU) standard (0) 0: 0 Location: Public network serving the local user (2) Ext: 1 Cause: Unallocated (unassigned) number (1), class = Normal Event (0) ] [1e 02 84 88] Progress Indicator (len= 4) [ Ext: 1 Coding: CCITT (ITU) standard (0) 0: 0 Location: Public network serving the remote user (4) Ext: 1 Progress Description: Inband information or appropriate pattern now available.

i tried without yellow as well.. and according to zaptel drivers, the yellow don't do anything, just put a yellow signal where there is nothing from the provider. and yes, i did put a pri_net on the span 2, the config is a typo.. thanks for reminding me.. but still i got those errors :( Leo Ann Boon wrote: snip zaptel.conf --- loadzone=uk defaultzone=uk span=1,1,1,ccs,hdb3,crc4,yellow span=2,0,1,ccs,hdb3,crc4,yellow I don't think yellow alarm is necessary unless you've been advised by your carrier. bchan=1-15,32-46 dchan=16,47 bchan=17-31,48-62 --- where span 1 is to the provider and span 2 is to the PBX zapata.conf - context=from-pstn switchtype=dms100 signalling=pri_cpe callerid=asreceived group=1 callgroup=1 pickupgroup=1 rxgain=0.0 txgain=0.0 channel=1-15,17-31 context=from-pstn switchtype=dms100 signalling=pri_cpe If you are connecting the second span to the 11c, shouldn't this be pri_net? And, since you're using E1 I believe both your switchtype should be euroisdn instead of dms100.

yes.. did that, still the same.. again, just to highlight again my problem... problem is connecting asterisk to the provider. have no problem from nortel to asterisk. i cam route all calls thru SIP. but i wan to route locals calls back to the provider.. :( this really gives me headache..

Have you tried swapping the spans?

Re: [asterisk-users] No D-channels available! Using Primary channel16 as D-channel anyway!
my problem now was with asterisk connecting to the provider..not asterisk to PBX.. asterisk to PBX is flawless anyway, was using what u suggested sometime ago, later found out i can collapse into one, then use it from then..

Then when another span is detected check for the bchan, dchan, fxoks, etc. to follow. I don't know if that is the case or not with zaptel drivers. zapata.conf - context=from-pstn switchtype=dms100 signalling=pri_cpe callerid=asreceived group=1 callgroup=1 pickupgroup=1 rxgain=0.0 txgain=0.0 channel=1-15,17-31 I would assume that you have an entry declaring a different context and group for your PBX, i.e.: context=from-pbx switchtype=dms100 signalling=pri_net group=2 callgroup=2 pickupgroup=2 rxgain=0.0 txgain=0.0 channel=32-46,48-62 Hope this points you in the right direction.
