[asterisk-users] Asterisk on multi-homed systems

I have zero issues with multihomed asterisks.

One potential issue is that some people are multihoming onto the same subnet.
This will cause issues with many applications as normal routing usually sends data OUT the lower IP address if there are two on the 
same subnet.

Multihoming, as a rule should be on separate network.

My company's implementation is one three networks.
One inside, One to ISP A and one to ISP B.

Like I said, I have had zero issues.
