Hello all, By standing on the shoulders of others, I am running a chanss7 asterisk (Asterisk SVN-trunk-r111909 ) server e1 itu ss7 link to a msc (lgc) and have now successfully been able to get calls to flow with sound and dtmf via sip out from the msc to pstn, all seems stable - but in the logs on occasion the following is stated - app_dial.c:759 wait_for_answer: Unable to write frame Is this of major significance ? Also in the asterisk msg log on startup is: [Apr 6 20:43:49] WARNING[5574] chan_zap.c: Ignoring hasvoicemail at line 27. [Apr 6 20:43:49] WARNING[5574] chan_zap.c: Ignoring vmsecret at line 31. [Apr 6 20:43:49] WARNING[5574] chan_zap.c: Ignoring hassip at line 35. [Apr 6 20:43:49] WARNING[5574] chan_zap.c: Ignoring hasiax at line 39. [Apr 6 20:43:49] WARNING[5574] chan_zap.c: Ignoring hasmanager at line 47. Again is this something to be concerned by? Thanks for any advice Magnus Linkset log below [ d2 cb 0d ] Network Indicator: 3 Priority: 0 User Part: ISUP (5) [ c5 ] OPC 1024 DPC 1025 SLS 5 [ 01 04 00 51 ] CIC: 69 [ 45 00 ] Message Type: REL [ 0c ] --VARIABLE LENGTH PARMS[1]-- Cause Indicator: Coding Standard: 0 Location: 5 Cause Class: 1 Cause Subclass: 0 Cause: Normal call clearing (16) [ 02 85 90 ] Len = 12 [ cb d3 09 c5 00 44 00 51 45 00 10 00 ] FSN: 83 FIB 1 BSN: 75 BIB 1 >[0] MSU [ cb d3 09 ] Network Indicator: 3 Priority: 0 User Part: ISUP (5) [ c5 ] OPC 1025 DPC 1024 SLS 5 c7asteri[ 00 44 00 51 ] CIC: 69 [ 45 00 ] Message Type: RLC [ 10 ] Len = 38 [ d3 cc 23 c5 01 04 00 61 46 00 01 00 00 00 0a 00 02 0a 08 82 10 70 17 51 09 13 01 0a 08 82 10 70 98 12 11 10 05 00 ] FSN: 76 FIB 1 BSN: 83 BIB 1 <[0] MSU [ d3 cc 23 ] Network Indicator: 3 Priority: 0 User Part: ISUP (5) [ c5 ] OPC 1024 DPC 1025 SLS 6 [ 01 04 00 61 ] CIC: 70 [ 46 00 ] Message Type: IAM [ 01 ] --FIXED LENGTH PARMS[4]-- Nature of Connection Indicator: Satellites in connection: 0 Continuity Check: Check not required (0) Outgoing half echo control device: not included (0) [ 00 ] Forward Call Indicators: Nat/Intl Call Ind: call to be treated as a national call (0) End to End Method Ind: no end-to-end method(s) available (0) Interworking Ind: no interworking encountered (0) End to End Info Ind: no end-to-end information available (0) ISDN User Part Ind: ISDN user part not used all the way (0) ISDN User Part Pref Ind: ISDN user part preferred all the way (0) ISDN Access Ind: originating access non-ISDN (0) SCCP Method Ind: no indication (0) [ 00 00 ] Calling Party Category: Category: Ordinary calling subscriber (10) [ 0a ] Transmission Medium Requirements: Speech (0) [ 00 ] --VARIABLE LENGTH PARMS[1]-- Called Party Number: Nature of address: 2 NI: 0 Numbering plan: 1 Address signals: 07711590311 [ 08 82 10 70 17 51 09 13 01 ] --OPTIONAL PARMS-- Calling Party Number: Nature of address: 2 NI: 0 Numbering plan: 1 Presentation: 0 Screening: 0 Address signals: 07892111015 [ 0a 08 82 10 70 98 12 11 10 05 ] Len = 14 [ cc d4 0b c5 00 44 00 61 46 00 06 40 14 00 ] FSN: 84 FIB 1 BSN: 76 BIB 1 >[0] MSU [ cc d4 0b ] Network Indicator: 3 Priority: 0 User Part: ISUP (5) [ c5 ] OPC 1025 DPC 1024 SLS 6 [ 00 44 00 61 ] CIC: 70 [ 46 00 ] Message Type: ACM [ 06 ] --FIXED LENGTH PARMS[1]-- Backward Call Indicator: Charge indicator: 0 Called party's status indicator: 0 Called party's category indicator: 0 End to End method indicator: 1 Interworking indicator: 0 End to End information indicator: 0 ISDN user part indicator: 1 Holding indicator: 0 ISDN access indicator: 1 Echo control device indicator: 0 SCCP method indicator: 0 [ 40 14 ] Len = 13 [ cc d5 0a c5 00 44 00 61 46 00 2c 03 00 ] FSN: 85 FIB 1 BSN: 76 BIB 1 >[0] MSU [ cc d5 0a ] Network Indicator: 3 Priority: 0 User Part: ISUP (5) [ c5 ] OPC 1025 DPC 1024 SLS 6 [ 00 44 00 61 ] CIC: 70 [ 46 00 ] Message Type: CPG [ 2c ] --FIXED LENGTH PARMS[1]-- Event Information: In-band information or an appropriate pattern is now available [ 03 ] Len = 16 [ d5 cd 0d c5 01 04 00 61 46 00 0c 02 00 02 85 90 ] FSN: 77 FIB 1 BSN: 85 BIB 1 <[0] MSU [ d5 cd 0d ] Network Indicator: 3 Priority: 0 User Part: ISUP (5) [ c5 ] OPC 1024 DPC 1025 SLS 6 [ 01 04 00 61 ] CIC: 70 [ 46 00 ] Message Type: REL [ 0c ] --VARIABLE LENGTH PARMS[1]-- Cause Indicator: Coding Standard: 0 Location: 5 Cause Class: 1 Cause Subclass: 0 Cause: Normal call clearing (16) [ 02 85 90 ] Len = 12 [ cd d6 09 c5 00 44 00 61 46 00 10 00 ] FSN: 86 FIB 1 BSN: 77 BIB 1 >[0] MSU [ cd d6 09 ] Network Indicator: 3 Priority: 0 User Part: ISUP (5) [ c5 ] OPC 1025 DPC 1024 SLS 6 c7asteri[ 00 44 00 61 ] CIC: 70 [ 46 00 ] Message Type: RLC [ 10 ] [Apr 6 20:26:54] WARNING[4140]: app_dial.c:759 wait_for_answer: Unable to write frame Len = 12 [ d6 ce 09 c1 01 04 00 31 11 20 06 03 ] FSN: 78 FIB 1 BSN: 86 BIB 1 <[0] MSU [ d6 ce 09 ] Network Indicator: 3 Priority: 0 User Part: STD_TEST (1) [ c1 ] OPC 1024 DPC 1025 SLS 3 c7asteri[ 01 04 00 31 ] H0: 1 H1: 1 [ 11 ] -------------- next part -------------- An HTML attachment was scrubbed...
