VOIP CODECSEXPLAINED
VoIP codecs compress and decompress audio for transmission over IP networks. The right codec configuration balances call quality with bandwidth efficiency. PTG optimizes codec settings for crystal-clear business calls.
Common VoIP Codecs
PTG configures optimal codec priorities based on your network capacity and call quality needs.
G.711 (Uncompressed)
Highest quality audio at 64 Kbps per call. Ideal for offices with ample bandwidth. Industry standard for toll-quality voice.
G.729 (Compressed)
Near-toll-quality audio at only 8 Kbps per call. Best for bandwidth-constrained connections or high call volumes.
Opus (Wideband)
Modern adaptive codec with HD voice quality. Adjusts bitrate dynamically based on network conditions.
G.722 (HD Voice)
Wideband audio at 64 Kbps providing noticeably richer sound than G.711. Supported by most modern IP phones.
Codec Questions
Which codec should my business use?
It depends on your bandwidth and phone hardware. PTG evaluates your network and configures codec priorities that maximize quality within your bandwidth constraints.
Do codecs affect call quality?
Yes. Higher-bandwidth codecs like G.711 deliver better audio but use more bandwidth. PTG configures Quality of Service (QoS) to ensure voice packets get priority.
Can different phones use different codecs?
Yes. Codec negotiation happens automatically between endpoints. PTG configures preferred codec lists so phones select the best available option for each call.
