What it is
xtelsio CTI Client is Windows software for computer-assisted telephony and contact management. Its PhoneDialog supports call answering, call history, speed dial, contact lookup, and call notes. Contact sources include classic Outlook, Google Contacts, Lotus Notes, ACT!, CardDAV, ODBC databases, LDAP, and CSV files. The vendor says the 2025 New Outlook is not supported.
