ISDN over IP ist ein Integrated Services Digital Network (ISDN), das auf dem Internet Protocol (IP) basiert. Im Unterschied zu anderen Varianten der IP-Telefonie setzt die Technik des Unternehmens Agfeo nicht nur die B-KanΓ€le um, sondern auch den D-Kanal, wodurch die vermittlungstechnischen Leistungsmerkmale zur VerfΓΌgung stehen,cite-ref-1[1] ausgenommen RΓΌckruf bei Besetzt (CCBS).cite-ref-2[2] Auf diese Weise ein komplettes ISDN zu schaffen, dessen unterste Protokollschicht von einem anderen Netzwerk geliefert wird, ist konform zum Referenzmodell der International Telecommunication Union.cite-ref-3[3]
ISDN over IP ermΓΆglicht, ΓΌber das Internet mehrere Telefonanlagen zu koppeln und HeimarbeitsplΓ€tze anzubinden, ohne dass die rΓ€umlichen AbstΓ€nde anschlieΓend wahrnehmbar sind.
