Abstract

A method and system for providing voice calls in a macro wireless network includes providing at a router of the micro wireless network an interface for communication with a service node of a macro wireless network coupled to the micro wireless network. The interface is of a same type as is used by a radio access network of the macro wireless network to communicate with the service node. A real-time protocol communication path is established from the interface through a voice module of the service node to a public switch telephone network. Voice traffic is communicated to the public switch telephone network through the interface and the real-time protocol path.
