Note:
AltiGen IP Phone extension users should not activate their IP
Phone by logging into voicemail — instead, #27 should be
used to log in.
Setting VoIP Codecs
The default codec for static IP extensions is G.711 with 64 kbps for voice
packets. This is appropriate for lease lines or high-speed connections. The
default codec for dynamic IP extensions is G.723 with 6.3 kbps. This is
appropriate for internet connections. For voice, G.723 AB uses 8 kpbs.
• G.711/G.723/G.729 bandwidth requirements:
(for example, a Multilink Point-to-Point Protocol (MLPPP) or Frame
Relay Forum (FRF), with no Voice Activity Detection (VAD)
running)
— G711 10ms packet frame = 100.8 kbps
— G711 20ms packet frame = 82.4 kbps
— G711 30ms packet frame = 76.3 kbps
— G723 30ms packet frame 6.4k rate = 18.7 kbps
— G729 20ms packet frame = 26.4 kbps
— G729 30ms packet frame = 20.3 kbps
You can change these defaults settings for AltiServ-to-AltiServ
connections using the VoIP Codec Configuration window.
