The minimum internet connection speed required for VoIP is between 90 kbps to 156 kbps. Your phones need a consistent, reserved amount of bandwidth for an excellent call and fax quality.

How much bandwidth is needed for a phone call?

Bandwidth is measured in kilobytes per second (kbps) or megabytes per second (MBps). Most calls require around 64kbps of bandwidth and you can make around 12 calls concurrently using 1mbps of bandwidth and to be able to hold 120 calls at the same time you’d need 10Mbps of bandwidth.

How much bandwidth does a Cisco IP phone use?

With circuit-switched voice networks, all voice calls use 64 Kbps fixed-bandwidth links regardless of how much of the conversation is speech and how much is silence. With VoIP networks, all conversation and silence is packetized. With Voice Activity Detection (VAD), packets of silence can be suppressed.

Calculating Bandwidth Requirements for VoIP Calls

  1. Total packet size = headers + voice payload size.
  2. PPS = (codec bit rate) / (voice payload size)
  3. Bandwidth = total packet size * PPS.

Is 4G good enough for VoIP?

4G, in contrast, delivers 13.6 Mbits on average, with speeds greater than 2 Mbits almost 94 percent of the time – more than enough for consistent VoIP calls. Importantly, the latency (i.e. the time for a packet of data to travel from the user to the server) on 4G is below 0.1 second almost 99 percent of the time.
