A technique for requesting and providing in-call services encompasses a method of calling an information service during an ongoing call between two or more call parties. The method comprises the steps of receiving, during the ongoing call, a message from a first call party, determining that the message requests the provision of information associated with a second call party, obtaining a first identifier indicative of the second call party and sending a service request including the first identifier to the information service.
