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.

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.

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

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.
