The ECSTA for SIP Phones TAPI drivers can contact uaCSTA Server for SIP Phones through two different network interfaces. Both interfaces support TCP and TLS connections. UDP is not supported because of problems with packet fragmentation in large CSTA messages. For TLS connections, a certificate issued to the computer name must be provided, which is trusted by the ECSTA for SIP Phones TAPI drivers.
With the WAN interface, an IP address different from the DNS name can be stored in the port setting. Enter the public IP address (DNS-Name) port through which uaCSTA Server for SIP Phones will be accessible from the Internet. If the computer does not have a public IP interface itself, the entries will not be needed here.
You can only make changes to the connection settings when the Server Service
has been shut down.
