What type of Internet connection does VoIP require?
VoIP can run on any IP network, but for business quality calls, it’s generally recommended that businesses consider a high speed network like a T1 line. Cable and DSL connections often don’t provide enough upstream bandwidth to sustain voice quality. Small businesses should look for a vendor that places an emphasis on voice quality and backs that emphasis up with metrics driven service level agreements (SLAs). SLAs should cover service quality metrics such as jitter and packet loss that directly impact voice quality.
