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.
Thanks,
Matt
