Requirements

Installation and Operation

uaCSTA Server for SIP Phones and ECSTA for SIP Phones can be used on 32- & 64-bit Windows® operating systems. Both products can be installed on the same computer. If other SIP applications have been installed on the computer on which the server should be installed, the usage of the default SIP and SIPTLS ports (5060 & 5061) must be checked. If these ports are already in use, you will have to use other ports available.

Supported Operating Systems:

Windows® 10
Windows® 11
Windows Server® 2012
Windows Server® 2012 R2
Windows Server® 2016
Windows Server® 2019
Windows Server® 2022

Communication with Telephones

In order that uaCSTA Server for SIP Phones can communicate with the telephones, they will have to be registered with the server. To do this, a SIP identity, through which the telephone will be registered with the server, must be configured on each telephone to be controlled. These settings can be stored in the telephone through the Provisioning dialog integrated into the Administrator. As soon as the telephone registers itself with the server, it can be monitored and controlled. Environments in which the telephones are found in a VLAN or physically separated network are supported. To do this, the server must be integrated into this network using a network interface. You will find detailed information about the configuration of the IP interface and the login information in the settings for the Telephone Connection.

Communications with ECSTA for SIP Phones

ECSTA for SIP Phones will contact the server analogously to the telephones. Here too, the client must be able to contact the server. You will find detailed information about the configuration of the IP interfaces and the login information in the settings for the Client Connection.
