Is there a way to have an MGCP gateway preserve existing calls when it enters Fallback mode and reverts to H323? One of our senior VP's was at a remote site when the MPLS circuit dropped out and they were kicked off an important conf call when the gateway switched over (They were able to re-dial in once it was in fallback mode)
Basically I've been ordered to never let this happen again and I'm not relishing the thought of converting about a dozen MGCP gateways over to H323 just to accomplish this.
Is there a better way? :)
