Hello List I'm trying to figure out what is wrong between my asterisk and my NEC 2400 pbx We have been trying to link them with a spare PA-24DTG from the NEC, I'm able to call an extension on the Asterisk, however the extension rings, and then immediatly hangs up I traced it back to the debug of the PRI on the Asterisk...
I would appreciate if anyone could pin point what is wrong The error code: Cause: Mandatory information element is missing (96), does not tell me what is missing, so any expert outthere who could give me some direction would be extremely helpfull. dadhichannel.conf context=from-internal switchtype = national signalling = pri_net channel => 1-23 context = default group = 63 system.conff span=1,1,0,esf,b8zs # termtype: te bchan=1-23 dchan=24 echocanceller=mg2,1-23 Thanks *Trace:* Enabled debugging on span 1 < Protocol Discriminator: Q.931 (8) len=27 < Call Ref: len= 2 (reference 99/0x63) (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) < User information layer 1: u-Law (34) < [18 04 e9 80 83 01] < Channel ID (len= 6) [ Ext: 1 IntID: Explicit PRI Spare: 0 Exclusive Dchan: 0 < ChanSel: As indicated in following octets < Ext: 1 DS1 Identifier: 0 < Ext: 1 Coding: 0 Number Specified Channel Type: 3 < Ext: 0 Channel: 1 ] < [1e 02 80 81] < Progress Indicator (len= 4) [ Ext: 1 Coding: CCITT (ITU) standard (0) 0: 0 Location: User (0) < Ext: 1 Progress Description: Call is not end-to-end ISDN; further call progress information may be available inband.
