We are trying to connect asterisk with our Merlin Legend. Everything looks good but calls wont go through (get fast busy in both sides): Here is a pri debug of an outgoing call: --- snip --- -- Making new call for cr 32778> Protocol Discriminator: Q.931 (8) len=45 > Call Ref: len= 2 (reference 10/0xA) (Originator) > Message type: SETUP (5) > [04 03 80 90 a2] > 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: u-Law (34) > [18 03 a1 83 81] > Channel ID (len= 5) [ Ext: 1 IntID: Implicit, PRI Spare: 0, Preferred Dchan: 0 > ChanSel: Reserved > Ext: 1 Coding: 0 Number Specified Channel Type: 3 > Ext: 1 Channel: 1 ] > [28 0d b1 56 69 63 74 6f 72 20 50 65 72 65 7a] > Display (len=13) Charset: 31 [ Victor Perez ] > [6c 06 21 80 34 33 30 35] > Calling Number (len= 8) [ Ext: 0 TON: National Number (2) NPI: ISDN/Telephony Numbering Plan (E.164/E.163) (1) > Presentation: Presentation permitted, user number not screened (0) '4305' ] > [70 05 a1 34 31 38 39] > Called Number (len= 7) [ Ext: 1 TON: National Number (2) NPI: ISDN/Telephony Numbering Plan (E.164/E.163) (1) '4189' ]-- Called g2/4189 < Protocol Discriminator: Q.931 (8) len=9 < Call Ref: len= 2 (reference 32778/0x800A) (Terminator) < Message type: RELEASE COMPLETE (90) < [08 02 81 91] < Cause (len= 4) [ Ext: 1 Coding: CCITT (ITU) standard (0) 0: 0 Location: Private network serving the local user (1) < Ext: 1 Cause: User busy (17), class = Normal Event (1) ] -- Processing IE 8 (cs0, Cause) -- Channel 0/1, span 1 got hangup pbx*CLI> -- Zap/1-1 is busy NEW_HANGUP DEBUG: Calling q931_hangup, ourstate Null, peerstate Null NEW_HANGUP DEBUG: Destroying the call, ourstate Null, peerstate Null -- Hungup 'Zap/1-1' [Kpbx*CLI> == Everyone is busy/congested at this time --- snip --- zaptel.conf: ----------------- span=1,1,0,esf,b8zs bchan=1-7 unused=8-23 dchan=24 fxsks=25-26 loadzone=us defaultzone=us zapata.conf ------------------ switchtype=5ess signalling=pri_net ; rxwink=300 group=2 channel => 1-7 The ML's T1 is set as PRI/Legend-Ntwk and is the last card in the switch having only 8 available trunks. That is why I am only using 7 b-channels. I am guessing that the ML would put its d-channel elsewhere but when I try changing dchan to anything but 24 asterisk won't start with: Unable to open D-channel 24 (No such device or address) Unable to start D-channel on span 1 Is this a d-channel problem or something else? I was using 1.0-stable but I upgraded to 1.0.2 without differences. (btw, verbose output is totally messed up in 1.0.2) Thanks in advance, Victor Perez

Try pridialplan=unknown in your Asterisk zaptel.conf file. What about a trace of a call coming from the merlin in?
