I would appreciate some help here.

 

Thanks

[SupportTeam]

Call was dropped as the Dialogic card reported that there was Loop Current drop on the line.

By default Loop Current drop is treated as an indication of end of call and hence VG hangs up.

 

This is either because the telephone company (or PBX) is doing a Loop Current drop or because the cable itself is faulty and intermittently causes a break in actual wire connections (which stops flow of current through the wire loop).

 

You should ask your telephone company if they are doing a loop current drop on the line during a call and if yes then ask them to stop doing this midway though a call.

 

You could disable VoiceGuide's reaction to Loop Current drop:

 

In VG.INI, in section [CallControl] set

 

LoopCurrentDrop=ignore

 

and in ConfigLine.xml file make sure the SendDisconnectOnLoopCurrentDrop rule is set to value of 0. Like this:

 

<rule>

<Description>Do we send Disconnect on Loop Current Drop</Description>

<Key>SendDisconnectOnLoopCurrentDrop</Key>

<Value>0</Value>

<Default>0</Default>

</rule>

 

but note that Loop Current drop is used on analog lines to indicate end of call - and if it is not reacted to then the Dialogic card will need to be configured to listen for Disconnect tones to detect end of call See: http://www.voiceguide.com/vghelp/html/Disc...ctionDetect.htm

 

 

Which version of VoiceGuide are you using? You should be using the latest VG for Dialogic.
