HSRP) where you cannot transfer calls to the desired endpoint and callers lose connectivity.

Include all your IOS gateways in your zone as transfer candidates. You can prioritize them using the
gw-priority on the “zone prefix” commands. By using all the gateways in the zone, the possibility of not
finding a registered gateway immediately after HSRP failover are virtually eliminated, provided the
gateway dial- peers are configured as defined in the following bullet.
