Hello Experts An interesting problem to solve for which I'm having a hard time figuring out the solution myself.
We have a Call Manager node and IP Phones in one location and ingress voice gateways in other location. Both locations are connected over redundant WAN links. When one WAN link fails, it takes upto 5 seconds for the redundant WAN link to kick in. Issue is, if there is an active call between the gateway and the IP Phone, the call simply drops when a WAN issue occurs. Is there a way to preserve the RTP stream on the GW itself that can be resumed once the redundant WAN link takes over? Any input is appreciated!
