SBC Suggestion - IPO with 1 SIP Trunk Connected to Router with WAN Failover

[Brian Elias]

I have a small business customer (~ 100 employees) all at a central location. They use an IPO500v2 that I have configured with a single Flowroute SIP trunk.

The IPO connects via LAN to a Meraki MX firewall, which handles QOS and dual WAN failover.

The issue has been discussed here quite a bit...I can't figure out a way to have this configuration survive a WAN failover event (since the Public IP changes).

After reading through the posts, it seems like an SBC is the way to go. I checked the Audiocodes / Mediant 500, but I don't how this unit would survive a Public IP change either. When I look at the wizard, it seems to only allow for a single Public IP through NAT.

Is there something I'm missing with the Mediant, or a different SBC to use?


Thanks,


Brian

ASBCE can have two IPs on the public interface. If you create two different server flows you can use each interface IP in one flow. With the MX you should be able to route traffic from one SBC IP to the first WAN connection and traffic from the second SBC IP to the second WAN. The SBC can know the zwei public IPs then.
