3300Mxe: Ghost calls - dropped when picked up

[pichels]

Hi,

We have an issue where the Receptionist/Operator is using the 5550 IP console and a source call comes in from the PRI, I think, to our main line and can be any trunk or COS and she picks up the call and there is no one there?

She can't get much more info in the console screen since the process flashes up so fast on the first or second ring and then nothing.

We had our vendor check the system/software logs and found some DS1 formatter PLID's in the releasing state?

We checked on these ghost calls from this morning and the entries above were only relevant to that time period.

If you need more details on the log entries - I can copy/paste more later - the vendor is using the console right now...
The vendor wants to reboot the 3300 and I'm not sure that is relevant.

Please advise or let me know if I can setup more verbose debugging or logging.

Thanks in advance.

is your system being answered by auto att

call like that can be a sign of potential hacking / attempts at toll fraud

Hi guys-

Yep - being answered by auto attendant.

Well - I wouldn't discount hacking - I asked the tech about that possibility ans he was unsure.

The tech thinks the issue was 4 channels in a locked out/releasing state in Software log.

Couldn't RTS and so the ticket went to the phone service provider with PRI-Circuit ID.

Thaks for your help.

You should see if there is any kind of Call ID. In my experience, It might even be voicemail ports calling back to the operator if they are stuck in a loop. This happens when the VM ports are given a call re-route first alternative of voicemail. The vm ports should not re-route at all. have you tech check on this as well.

Could be a number of things. Have seen a issue with the embedded VM and it calling 0. Required a software upgrade to fix. Are intercepts sent to the console? Also do you have copper trunks pointed to the Attendant?

Hi again,

Yes - there was an issue with VM ports in the past and ringing the console.
But, the vendor fixed that issue.

However, we received less calls now after the Service provider kill the connections a week or so ago.
I'm not sure if they are still happening - I'd have to check with the receptionist.

Intercepts may be sent to the console - not sure how to check that.
Trunks are copper I believe - but I'm not sure if they are pointed at the attendant.

Thx for the responses.
I'll try to update more later - not a priority right now.
