Disconnected Number Detection

[edooze]

Hi Guys,

I run a small callcenter with under 5 agents. I am using ViciBox.
From the GUI:
VERSION: 2.8-418a
BUILD: 131029-2008

VICIDIAL calls go out through FreePBX for reasons that are not important to this conversation.

I am having troubles with disconnected number detection, and it seems after Googling for a while I'm not alone. VICI (and, it would seem, asterisk in general) only gets silence from the provider instead of the disconnected signal, because the provider chooses to do nothing with whatever response they get back from the PSTN carrier (correct me if I'm wrong, but I believe this is what's occurring).

I have, after a lengthy conversation with my provider, got them to offer me a setup whereby they will pass 503 and 404 codes through to my PBX. I'm not sure how I would go about configuring VICIdial to do anything with them, or even if they'd be any use etc.

Can someone please shed some light on how I could make use of this? Or point me in the right direction of how to organise correct DC number detection? I have a large list of numbers (~500,000) I'd like to throw at the autodialer, but can only realistically expect a 60% accuracy due to the age of the data. I'd like to not be calling DC numbers 4-6 times before they are dropped from the call list, as it will result in much agent downtime on a 29sec timeout.

TIA,
edooze.

I would suggest upgrading vicidial to get some better tools to be able to see the SIP cancel codes(using Admin Utilities). Also, passing the calls through another Asterisk server can cause you to have different results as compared to directly connecting to your carrier.

Thanks, Matt. I've just been able to perform the update to 2.10 today: very excited to see all the new features.
I'll look further into this and see what I can come up with. The double-edged sword of passing through another Asterisk server _should_ be that I can send Vici whatever codes it might need to mark numbers as DC. Either that or, not being a developer, I'm way off base. Would you mind shedding light on how Vici identifies DC numbers when using SIP? Is such a thing implemented? The research I have done to date suggests people tend to accept the silence, and auto-drop numbers that don't get answered after 4-6 attempts - hence my previous post. I'd like to do it a little differently if possible.

Thanks in advance.

Edit:
In case it's relevant, new version numbers:
VERSION: 2.10-461a

Try to enable "Enhanced Disconnect Logging" under system settings and see if that catches the DC numbers

Hi,

where we can see the "Enhanced Disconnect Logging" report??

thanks

[mflorell]

It's under System Settings. If you don't see it, you will probably need to upgrade to a more recent version of Vicidial.

[santhuarnold]

option is enabled but where we can see the log report?
means will get that logs in CDR??

[DomeDan]

There is no special log for this option, its just a setting that changes the way vicidial handles disconnected calls.

but there is some logs under "admin tools" in the bottom of the report page
