Carrier load balancing between their two SBCs

[Ronan]

I have to look at this. I have 2 SIP peers from the telco, two 3300 IPBX for redundancy, but only one MBG.

Calls come on the first SIP peer, if I shutter the first IPBX, calls get to the resilient phones. If I shutter the first SIP peer, it works too. However, I can't emit calls from the second IPBX to either SIP peers, only incoming works.

If only the client wasn't so cheap and had forked for another MBG !

If I understand you correctly, all incoming calls work OK, probably load balanced between your two 3300 controllers.
But you're having trouble load balancing outbound?  Is that correct?

You won't be able to load balance outbound.  Best you'll be able to do is route all your outbound traffic out one SBC until it's maxed out and then overflow to the second one.
