Abstract
A method of call control in which a first communications network, detecting calls directed to a destination in the first network; redirects at least some of the calls to a destination in a second network (e.g. on no answer from the destination in the first network). The first communications network obtains from a client on a terminal associated with the destination in the second network a value for the time delay before a call to the destination in the second network is redirected in the second network on no answer to an alternative destination and sets a delay period to a value less than the value of the time delay obtained from the client. When one of the plurality of calls redirected to the second network is not answered in the second network within the delay period, the first communications network redirects the call to an alternative destination associated with the first network.
