Abstract  Abstract

The invention relates to a method and system for establishing a first type of connection wherein a handshake processing is performed with the other party of the first type of connection. If the handshake processing is successful the first type of connection is established. If the handshake processing is not successful i.e. the other party does not support the first type of connection a fallback procedure is started to change the call to a second type of connection determined during the connection establishment. The change to the second type of connection may be performed directly or may be based on a call retry procedure. Thereby inconvenient disconnections or error processings at the end terminals can be prevented.
