Abstract
The present solution relates to providing a call service in a communication system, where in response to recognizing a predetermined event related to a user terminal (UEA), it is checked () whether the user terminal (UEA) is a roaming user terminal (UEA) roaming in a visited packet switched network. It is also checked () whether the user terminal (UEA) is defined to use a home network routing function in the visited packet switched network. If the user terminal (UEA) is a roaming user terminal (UEA) roaming in the visited packet switched network and defined to use the home network routing function in the visited packet switched network, the home network routing function is over overridden by performing () a forced setup of the call service to a local circuit switched network.
