NCH IVM Telephone Answering Attendant is on-premises telephone management software for small to medium businesses. It combines voicemail, call attendant, interactive voice response, and automated outbound calling for uses including answering, call routing, telephone surveys, order taking, and outbound messages. Incoming callers can hear menus that route calls or redirect them during or after office hours. The product lists support for as many as 64 telephone lines at once. Caller tools include caller ID logging, keypad menus, remote telephone access, and call transfer when supported by the phone company or PBX. IVM saves incoming messages as WAV files; voicemail boxes can forward messages by email or provide internet-page or remote access. It connects through a professional telephony board, TAPI-compliant voice modem, VoIP SIP service, or a PBX such as Axon. NCH says it can detect its Axon IP PBX on the same server and provides free plugins for ODBC/SQL, internet access, fax-back services, and hardware control. NCH offers a free trial download. Listed plans range from 6995.00 USD per once for Basic Answering Machine to 89900.00 USD per once for Enterprise; Professional is also offered for 2999.00 USD per month.
