Description:	When doing any sort of ISDN between an asterisk and Ascend TNT, asterisk barfs at missing 'Progress Indicator' IE in 'PROGRESS' ISDN message. This IE is currently marked as mandatory: { Q931_PROGRESS, "PROGRESS", { Q931_PROGRESS_INDICATOR } }, However, asterisk can be compiled with #define ALERTING_NO_PROGRESS which will not send progress-indicator with a progress IE, but it still will require progress-indicator from the peer. This looks like oversight - at minimum ALERTING_NO_PROGRESS should control it. I do not have Q931 docs, so I don't know if the spec requires it or not. Someone should check docs PRIOR to applying any fix ;) Fix: /*      { Q931_PROGRESS, "PROGRESS", { Q931_PROGRESS_INDICATOR } }, */        { Q931_PROGRESS, "PROGRESS"  }, ****** ADDITIONAL INFORMATION ****** < Protocol Discriminator: Q.931 (8)  len=10 < Call Ref: len= 2 (reference 32771/0x8003) (Terminator) < Message type: CALL PROCEEDING (2) < [< [18< [18 03< [18 03 a9< [18 03 a9 83< [18 03 a9 83 02< [18 03 a9 83 02] < 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: 0  Channel: 2 ] -- Processing IE 24 (cs0, Channel Identification) < Protocol Discriminator: Q.931 (8)  len=5 < Call Ref: len= 2 (reference 32771/0x8003) (Terminator) < Message type: PROGRESS (3)

If you got q931 specs - post them or forward to me, and I'll look it up. I don't have it - it isn't free... By: Mark Spencer (markster) 2004-10-27 20:59:15 According to Q.931 it *is* mandatory.
