What xtelsio CTI Client is
xtelsio CTI Client is Windows software for computer-assisted telephony, connecting phone controls with contacts from services and files many businesses already use. Its PhoneDialog provides 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. For calls, it works with TAPI-enabled phones and PBXs and has integrated connectors for Asterisk, FRITZ!Box, snom, Yealink, Mitel/Aastra, and Fanvil. Availability of controls such as hold, consultation, conference, and forwarding depends on the TAPI driver or phone. CTI Server adds presence management, shared speed dial panels, TeamChat, and an offline call journal. CTI Client 3.1 Standard and Professional have a 30-day trial; a limited-functionality freeware 2.2 lite edition is also listed, with one phone book capped at 200 entries. Listed workstation licenses are 33,00 EUR without VAT for Standard and 42,00 EUR without VAT for Professional.
