Dead Air/Unknown calls

I would like to get the communities feed back on this issue.

Certain users within our company (mostly linked to 800 numbers) continue to receive dead air phone calls. Is there a standard way of dealing with these calls?

I know that with an H323 environment you can block the number if you know the called number; however, our entire environment is setup as MGCP.

Do you guys have FXOs?

Enable CDR in CUCM

Check timestamps with CDR reports and contact Telco.

Re: Dead Air/Unknown calls

If the calls are from specific numbers you could configure a translation pattern to match the calling number and change the called number to a pilot for a Unity or UCCX message stating unsolicited 0800 calls are unwelcome.

Re: Dead Air/Unknown calls

Thank you for the idea, Could you give me a little more detail on how to create a translation pattern based on calling party? I see a section called "calling party transformations" however I am not sure how to set it up.
