FIELD: radio engineering, communication.
SUBSTANCE: method includes a step of generating an overload indication in a media gateway for resources on a route to a recipient through a first-type network, wherein the method further includes the following steps which are performed in a call management server of said communication system, where an overload indication is received, the overload indication associated with the route is stored, checking, after receiving the next call initiation request on the route, whether an overload indication for the route exists, and setting up a call on an alternative route to the recipient through a second-type network if said overload indication exists.
EFFECT: efficient use of a first-type network and a second-type network.
