Hi guys

Does anyone know if a Samsung OS7200, currently working with a single SIP trunk provider via Public IP address can be programmed with another separate SIP trunk for failover use?
Samsung say you can only have one Public IP in use at a time so you have to change it manually in menu 5.2.10.
But they also say it could possibly be achieved by letting a dual WAN router do the Natting and leave the system as PRIVATE ONLY.
Has anyone out there attempted such a thing, or is this an impossible dream?

Thanks in advance if anyone has an idea

Thanks

Mike
