From Wikipedia, the free encyclopedia
TelTel is a new generation of VoIP services that merge on-net and off-net calling services with presence information. Their TelTel softclient and backend service is based on the SIP (Session Initiation Protocol) and compatible with other SIP-based phones, such as Cisco SIP phones, D-Link Wi-Fi phones, Sipura phones, Linksys phones, Winstron Wi-Fi phones, UTStarCom phones, Leadtek phones and Grandstream phones. They claimed that their system is serving over 1,500,000 registered users.
