I have a customer that has several MGCP Gateways, some of which are behind some unstable WAN links. After the gateways lose connectivity to the Callmanager, they unregister (as expected) but when the link is restored, they lose all their MGCP configuration, and they have to be reconfigured to reconnect to the Callmanager.
Is this usual? unsual? This does not happen to the MGCP Gateways that are well-connected to the cluster.
Can anybody give me some advice?
