11,000 continuous minute conference bridge call!

[nitz01]

Our PRI provider is billing us for two simultaneous calls from the same number to our 1-800 number that appears to have terminated in the conference bridge on the IPOffice. That's over 7 days of continuous call time. Any idea how on earth this is even possible, and if we should be responsible for this?

 

[fonewiz]

Do you have DID pointed to this conference bridge? Are you PIN Checking or just allowing calls into your bridge unrestricted? If your not PIN Checking it is entirely possible for a call to just sit in the bridge.

 

[nitz01]

we do not have DID pointed and are pin checking via VMPro.

caller dials 1800 -> Auto Attend Answers -> Conference extension dialed -> Pin is prompted for -> Caller trans to bridge.

 

[CarGoSki]

They should be able to give you ID of the callers.

 

[nitz01]

yes i know the id of the caller. it's in the avaya logs and the PRI logs. if it is an intentional fraudulent call how does anyone make use of a two simulataneous and continuous open lines from the same number for 7 days?? to me this seems like a glitch that kept the lines open on either end. i'm trying to understand how and whether the PRI vendor is at fault or us.

Use the t shortcode
Then you can set a time in minutes so it will end the call after that time

[nitz01]

i'm not familiar with the "t" shortcode.

 

[CarGoSki]

Well if no one hangs up then why would a call automatically end?

So.. do you know the caller? Are they known to your company. I don't know what benefit a hacker could have using conf calls but you could upgrade to 5.0 to alleviate the issue.

I have seen where a call will stay up using the nouser profile. That was a bug back in the day. What version do you have?

 

[nitz01]

yes i'd imagine if neither party hung up the call would not terminate. that would be unlucky though. I can't upgrade to 5.x or 4.x because this is a 406v1. however, i am not on the latest 3.x.

manager reports 406 v1 running 3.0(69)

 

[CarGoSki]

I suppose one benefit to a hacker would be if the hosted conference had a toll free number pointed to it. Then folks could load up on a free party line.

you could upgrade to 5.0 to alleviate the issue."

did I miss a Feature? what would 5.0 do to alleaviate the issue? we have had customers have simmular problems, and went down the "T" option before.

thanks

System/Telephony

Drop External Only Impromptu Conference: Default = Off, Software level = 5.0+.
If selected, when the last remaining internal user in a conference exits the conference, the conference is ended, regardless of whether it contains any external callers. The Inhibit Off-Switch Forward/Transfer option above is no longer applied to conference calls. If not selected, the conference is automatically end when the last internal party or trunk that supports reliable disconnect exits the conference.


So a internal user is required to keep a conf call up.

 

[nitz01]

@vid151 - so you've come across this issue before? in my case no one could call into the conference bridge because it rang busy. this is how we were alerted to the problem.

this is the second time the "T" option is mentioned. can you elaborate on this and how to implement it?

 

[tlpeter]

Put it in your shortcode:

· t - Allowed Call Duration
Set the maximum duration in minutes for a call plus or minus a minute. Follow the character with the number of minutes in brackets, for example t(5).


So if you have this shortcode:

N
dial
N
0

Then it should look like:

N
dial
Nt(5)
0

Now your outgoing calls will be cut of after 5 minutes
