Is it possible to setup a 3430 with media anchoring with two external trunks, one to each provider, going to one PBX?
Basic plan is this:
1. setup existing carrier for inbound calling to fulfil the customer's existing contract.
2. add a trunk from our switch for some inbound and all oubound traffic. Is it possible to have the AOS device control which trunk outbound calls go to ? Failover to the other trunk if one is unavailable?
Can this be done with a single IP address? Do we need multiple addresses ? Either scenario is possible.
