Method for switching between two telephony services

Method for switching between two telephony services

When two terminals (T1, T2) communicate with each other by a first service via a network, the first telephony service is switched to a second telephony service in such a way that the two terminals (T1, T2) can continue to communicate with each other via the second telephony service. In order to carr...

Zusammenfassung:When two terminals (T1, T2) communicate with each other by a first service via a network, the first telephony service is switched to a second telephony service in such a way that the two terminals (T1, T2) can continue to communicate with each other via the second telephony service. In order to carry out said switching, a telephony service transformer (6) interrupts the communication using the first telephony service between the terminals (T1, T2), calls the two terminals (T1, T2) in parallel via the second telephony service, connects the two terminals (T1, T2) by joining the two communications established between the transformer (6) and the two terminals (T1, T2) respectively in order to set up a communication between the two terminals (T1, T2) via the second telephony service.
