[asterisk-users] multiple provider for incoming

We have couple of stores with published phone numbers. We are currently using a telecom company that hosts those numbers and provides us with SIP trunking. 

Recently we experienced couple of outages with this company, so we are looking into getting a backup provider just in case. 

As far as I know it's straight forward to setup multiple providers in Asterisk, but I'm not quite sure how the incoming calls will work as far as the phone nos. Do we need to have the first provider temporarily forward the calls to the second provider's DIDs? What if first provider goes down completely?

This is not really an Asterisk question, but any help is appreciated.
