TAPI and more for the IP- desk phone
uaCSTA brings your desk phone (aktuell the manufacturer Yealink, Snom, Asom, Auerswald, Fanvil, Htec, Grandstream, Intelpras, Gigaset and soon Panasonic) to the computer screen and expands it with the most important interfaces of the computer world. User Agent C.computer Supported Telecommunications Applications (uaCSTA) form the basis of CTI, the Computer Telephony Integration, and thus connect the IP- phones via the network to the Computer.. This makes it easy to connect any TAPI-Software (z.B. https://tapicall.de) possible .
uaCSTA on the local PC
On your local computer, uaCSTA offers interfaces for Microsoft Outlook, LDAP server and any TAPI applications. With uaCSTA, the desk phone is operated almost entirely via the PC-screen. For incoming calls, the associated contact details are displayed in your CRM- software. CSTA-URLs show contact details in your web-customer administration.
Terminal server and home office
In everyday office life, the TAPI protocol is certainly the most important interface of all. uaCSTA is set up so that you can easily access your office software via a terminal server. The phone in the home office becomes a REAL office phone that communicates with the office software remotely. One push of a button in the customer management of the terminal server environment starts a phone call on the desktop device at home, displays the caller or assigns him to a process.
