[asterisk-users] Random dead calls

[Gopalakrishnan N]

Hi,

Am getting dead or silence calls at sometimes for my agents, when I checked
my CDR the caller-id shows my vendor's name and some shows as real customer
name.

When I call back again the real customer's number its reaching, the
answering machine owned by customer.

I have a confusion, or how to find out are these numbers are from any auto
dialer or from real customers.

Thanks.
