SIP Provider compatibility list and profiles

A large number of providers for SIP system connections are available for the connection to the public telephone network.

Enreach is testing a large number of national and international SIP providers to determine interoperability with Swyx and SwyxON and the functionality of the respective SIP connection. All SIP trunks have been successfully tested for the most important features.

For a complete configuration, individual settings may have to be made or special features of individual providers may have to be taken into account. This additional information is available via the corresponding link.
