Vg Call State "unavailable"

[mikhubb]

I am running VG4.9 on a P2-300 with 200Meg of ram with Win98.

 

Using an Aopen FM56-ITU modem with most recent drivers.

 

I have a VG script for a Football Pool that has been working fine through the many versions of VG. I am currently having a problem on a fairly regular basis (daily) where for no apparent reason the "Line State" goes "UNAVAILABLE" and the phone line sits "Busy" and no more calls are answered until I restart the system.

 

I have attached a couple of trace logs with the problem occurring at the very end of the trace log. I am also attaching a TapiWrap log that keeps being created in the c:\ directory. I will also include my VG.INI.

 

I hope this will give you enough information to determine the error and assist in correcting it.

 

 

P.S. Are you every going to post a detailed description of the VG.INI settings?

 

 

Thanks

If Window's Voice Modem driver (UnimodemV) stops receiving any responses from the modem it will report the line as "Unavailable" - if VoiceGuide receives this message from UnimodemV there really isn't much else that can be done... the modem driver has already tried it's best to get the modem working but to no avail...

 

Some modems are just not very reliable and we have seen this happen periodically with some modems. For a 24/7 service you should use a Dialogic card.

 

These communications problems seem to occur less under Win2000 then under Win95/98/ME

[Guest Guest_mikhubb]

I know you have the list of modems that work well and I can pick a Dialogic card out of the list, but since I am only using a single line but need the 24/7 is there a dialogic card that you would recommend for my specific type of setup and operating system over and above the rest?

 

Thanks.

[SupportTeam]

The entry level card is a D4PCI.

 

You can still purchase a 2 port ProLine/2V (it's an ISA card - so you'll need a computer which has ISA slots) 2nd-hand on Ebay.

 

Dialogic cards should not be used under Win98 - you will need WinNT or Win2000.

I find that the "unavailable" problem is very common, but that 98% of the time, simply exiting VoiceGuide & reloading it fixes the problem.

 

Is there an easy way to detect this state so that the program can be reset?

 

I noticed the following in the .ini file:

;VgControl.exe monitors Vgmulti performance, and will reset the system

;if it finds that the system is not processing calls correctly.

;For high reliablity systems it is recommended that VGControl be running

;at the same time as VgMulti.

;AssistingApp=VgControl.exe

...and decided to play with it, but it requires a CTMWrap.OCX file to function, for which I can find no info.

[SupportTeam]

For VoiceGuide to restart automatically when the TAPI driver reports the device as "Unavailable" please set the VG.INI entry "OnError_Unavailable" in section "[OnError]" to "RESTART_VOICEGUIDE"

 

ie:

 

[OnError]

OnError_Unavailable=RESTART_VOICEGUIDE

[mikhubb]

Insteresting. I tried both the "RESTART_TAPI" and "RESTART_VOICEGUIDE" and neither had any effect when my system hit the "unavailable" state.

 

Any comments?

 

It also seems that the "unavailable" state was somehow cause by my application using the "exit" command when there was an application error (i.e. file not found for ODBC).

 

Should I use the "hangup" command instead?

[SupportTeam]

Have just ran a test with v5.0 and confirmed that that version restarts when the line becomes "Unavailable" and RESTART_VOICEGUIDE is specified in OnError_Unavailable entry...

 

The "Unavailable" event was simulated by turning the modem off.

 

It also seems that the "unavailable" state was somehow cause by my application using the "exit" command when there was an application error (i.e. file not found for ODBC).

Is this situation reproducible?
