SupportTeam Report post Posted 07/12/2012 08:49 PM Traces show that Dialogic drivers are responding correctly when VoiceGuide opens all 92 ports on this system. When VoiceGuide instructs Dialogic to place a call the Dialogic drivers indicate that an outbound calls is being made, but after a few seconds the Dialogic drivers advise that call could not be made. The error returned for first attempted call is "Recovery on timer expire". This is an ISDN connectivity level problem. Recommend testing the ISDN trunk operation using Dialogic's ISDIAG test application. You may need to contact T1 trunk provider as well. ISDIAG can also be used to capture ISDN tracing on the trunk. Once ISDN issues have been resolved and ISDIAG can make/receive calls, then VoiceGuide would be able to use these trunks as well. 150856.968 5692 2 fn LineMakeCall(iLineId=2, ... 150856.984 5692 2 LineMakeCall TelDriver_LineMakeCall zsResult=[<result>ok</result><crn>41943133</crn>] 150904.953 5820 2 ev GCEV_DISCONNECTED crn=280005d 150904.953 5820 2 gc_ResultValue: event 0x826 received on ldev: 2 - Event caused by call control library specific failure 150904.953 5820 2 gc_ResultValue: GC_ISDN_LIB 0x826 received on ldev: 2 - Recovery on timer expire 150904.953 5820 2 CTelProxy::Event_CallState GCEV_DISCONNECTED iLineCallState=16384, hCall=41943133 m_pktTelProxyClient=0067116C 150904.953 5820 2 r CallState GCEV_DISCONNECTED The second call attempt results in some unknown ISDN error being received. Looks like Dialogic drivers then place the channels on that T1 trunk in and out of service a number of times, which results in series of GCEV_SETCHANSTATE messages. 151017.453 5692 2 fn LineMakeCall(iLineId=2, ... 151017.453 5692 2 LineMakeCall TelDriver_LineMakeCall zsResult=[<result>ok</result><crn>41943134</crn>] 151017.468 5820 2 ev GCEV_DIALING crn=280005e crn_lastMakeCall=280005e 151017.468 5820 2 CTelProxy::Event_CallState GCEV_DIALING iLineCallState=16, hCall=41943134 m_pktTelProxyClient=0067116C 151017.468 5820 2 r CallState GCEV_DIALING 151021.546 5820 2 ev GCEV_DISCONNECTED crn=280005e 151021.546 5820 2 gc_ResultValue: event 0x826 received on ldev: 2 - CCLIB specific 151021.546 5820 2 gc_ResultValue: GC_ISDN_LIB 0x826 received on ldev: 2 - Unknown ISDN Error 151021.546 5820 2 CTelProxy::Event_CallState GCEV_DISCONNECTED iLineCallState=16384, hCall=41943134 m_pktTelProxyClient=0067116C 151021.546 5820 2 r CallState GCEV_DISCONNECTED 151021.546 5820 2 ev GCEV_SETCHANSTATE 151021.546 5820 4 ev GCEV_SETCHANSTATE 151021.546 5820 7 ev GCEV_SETCHANSTATE 151021.562 5820 10 ev GCEV_SETCHANSTATE 151021.562 5820 13 ev GCEV_SETCHANSTATE 151021.562 5820 16 ev GCEV_SETCHANSTATE 151021.562 5820 19 ev GCEV_SETCHANSTATE 151021.562 5820 22 ev GCEV_SETCHANSTATE 151021.562 5820 25 ev GCEV_SETCHANSTATE 151021.562 5820 28 ev GCEV_SETCHANSTATE 151021.562 5820 31 ev GCEV_SETCHANSTATE 151021.562 5820 34 ev GCEV_SETCHANSTATE Log shows the errors received on this trunk are: 150904.953 5820 2 gc_ResultValue: GC_ISDN_LIB 0x826 received on ldev: 2 - Recovery on timer expire 151021.546 5820 2 gc_ResultValue: GC_ISDN_LIB 0x826 received on ldev: 2 - Unknown ISDN Error 151051.796 5820 2 gc_ResultValue: GC_ISDN_LIB 0x826 received on ldev: 2 - Recovery on timer expire 151212.359 5820 2 cGC_ISDN_LIB 0x826 received on ldev: 2 - Data link is down The "Data link is down" error shows the D-channel of the ISDN trunk itself went down.
