Are you losing DIDs that terminate on your Asterisk box or your clients 
Asterisk box?

Are these DIDs registering with Asterisk and are you re-registering often 
enough?

Is it a problem within the providers? Can you port the DIDs to another 
provider?

Why do the DIDs stop working? Is is a connectivity problem you could 
detect with something like "ping" or "Nagios?"

Since you say "different providers" I'm thinking a general connectivity 
problem or something "generally" out of whack with registrations.

Thanks in advance,
