GotSpeech.NET

Hi -

I'm trying to figure out how to determine when a call has not been answered.  Currently, the gateway just lets the call ring and ring and ring, there is no cutoff, and I am not finding anything obvious as a gateway setting for this.  I'm using the DMG1008LSW (analog) for a gateway.  Is this a gateway setting somewhere, or do I need to set a time limit somewhere in my speech app?

Thanks.

Bring up the dialogic administration web page and click on VoIP, General in the Configuration section.  Change the “TCP Inactivity Timer” section to the desired number of seconds.  Each ring is equivalent to about 6 seconds.  I believe that will do it.

I don't have a VoIP tab on my administration website, I would guess because I'm using an analog gateway, as I do have an analog tab.  I did find that I'm not patient enough, that it does detect a no answer after about a 1.5-2 minutes.  It's a lot of ringing, and shortening that would be helpful I think.  Any more ideas?

Are you running the latest 6.0 version?  It ships configured with a previous software version.  You can download from the Dialogic web site.

Do you have an outbound call connect timeout under a configuration section?  I believe Marshall Harrison has an analog Dialogic gateway.

I'm not running 6.0 yet.  I do have an outbound call connect timeout, and have played around with that, but making it shorter means the gateway determines the call has connected after that period of time, and tells me the call has completed successfully, instead of me getting a telephony fault.

Maybe using the System.Threading.Timer can solve your problems if you start it at the beginning of the workflow and if a certain outcome is not met withing the specified interval, then disconnect the call. I don't know how well it can work because I have never tried it in WF.

You should hae a VOIP link on there someplace. I also suggest you follow Martial's advice and upgrade the firmware. It's really easy and the new interface is worth it.

Here are the settings I have on my Dialogic Gateway. Check the ones that I have bolded.

I just upgraded to the 6.0 firmware and have the VoIP tab now.  Since upgrading, I just tested out dialing again, and am seeing VOIP: Not Accepted as a fail reason.  Previously I was seeing TDM fail reasons.  I'm not set up for VoIP and don't know why I'm now attempting to use it.  I uploaded all the *,ini files by accident, would that have anything to do with this?

Marshell - thank you for your config information, my Analog Interface Type is PBX at the moment, since I'm interfacing with a PBX.  I couldn't tell if you were pointing me to actual configuration settings, or having me check them, as your setup includes all drop down information.

I got calling working again for my gateway, I needed to add another Inbound VoIP Rule for calls and it works again (whew!).  I did looka t the VoIP tab to see what my timeouts are for tcp inactivity timer (and tls inactivity timer) and they are both at 30 secs at the moment, though it takes 2 minutes to time out.

Under Config, VOIP, General, what do you have the invite expiration set to?

And now back to this one after a long break.  My invite expiration was set to 120 secs. I changed it to 36 secs, and that fixed my problem.  Thank you all very much!
