ISDN Migration

Our ISDN migration solutions transfer your ISDN system into a VoIP network environment. Existent infrastructure is not affected, but instead transferred on a one-to-one basis to a more cost-effective and efficient technology. Available ISDN connections remain fully preserved, while phone numbers remain unchanged. On request, even large quantities of new telephone numbers can be booked, naturally also in blocks. This is made possible by the method of SIP trunking which has emerged as the state of the art in recent years.
