VoIP replaces the phone line with a broadband internet connection, not dial-tone service. You need bandwidth of about 85 to 100 kbps per call and a device to talk on: an IP phone, a softphone app, or a regular phone on an adapter. You can k
A dedicated VoIP handset is optional. The same call can run through a softphone app on a phone or laptop, a purpose-built IP desk phone, a web browser using WebRTC, or your current analog phone plugged into an adapter. Each path needs an in
A VoIP call needs very little bandwidth, roughly 100 kbps in each direction, so the deciding factors are upload capacity and network quality rather than raw download speed. Aim for latency under 150 ms, jitter under 30 ms, and packet loss u
A landline carries your voice as an electrical signal over a dedicated copper circuit on the traditional phone network, while VoIP sends it as digital packets over your broadband internet. That split drives the rest: a landline keeps workin
VoIP carries calls as data over an IP network, so it needs connectivity to work. For any service that reaches outside callers or the public phone network, that means a broadband connection, though the link can be wired, Wi-Fi, or cellular d
At a minimum, VoIP needs broadband internet, an account with a VoIP provider, and one endpoint: an IP phone, a softphone app, or an analog phone with an adapter. A single call uses only about 100 kbps, but low latency and jitter matter more
Per-call VoIP bandwidth depends mostly on the codec. G.711 runs about 87 kbps in each direction once IP, UDP, and RTP overhead is added to its 64 kbps of audio, while G.729 compresses the same call to roughly 31 kbps. Adaptive codecs like O
A VoIP phone converts your voice into packets and sends them over broadband rather than a dedicated phone line. On power-up it registers to a call server with SIP, then streams audio as RTP packets compressed by a codec like G.711 or Opus.
A VoIP call follows a set sequence: your phone registers and SIP sets up the call, a codec digitizes and compresses your voice, RTP carries the audio as packets across the IP network, and the receiving end buffers, reassembles, and decodes
VoIP turns a phone call into digital packets that travel over an internet or broadband connection instead of a dedicated phone line. It reaches you as an analog adapter, a desk IP phone, a softphone app, a SIP trunk into a PBX, or a cloud p
