I have a prepaid calling card system that is starting to get a lot of use and I’m thinking that I may need to add an additional box in the future to handle the voice traffic.
How would you guys suggest I do this? I’ve never had a need to run the same app off of two different servers before. One thing I’m particularly worried about is the DID’s. How can I distribute the incoming calls to two different servers? Both boxes won’t be able to register with my VoIP providers, correct?
Any insight here would be appreciated!
