Number Assignment; Assigning Send And Receive Connections - Gigaset A510IP User Manual

You can also change the settings for the voice codecs yourself by selecting the
voice codecs to be used for each VoIP connection on your phone and specifying the
sequence in which they should be suggested when establishing a VoIP connection.
The following voice codecs are supported by your phone:
G.722
Excellent voice quality. The broadband speech codec G.722 works at the same
bit rate as G.711 (64 kbit/s per speech connection) but with a higher sampling
rate. This allows higher frequencies to be played back. The speech tone is there-
fore clearer and better than for the other codecs (High Definition Sound Per-
formance).
G.711 a law / G.711 μ law
Excellent voice quality (comparable with ISDN). The necessary bandwidth is 64
kbit/s per voice connection.
G.726
Good voice quality (inferior to that with G.711 but better than with G.729).
Your phone supports G.726 with a transmission rate of 32 kbit/s per voice con-
nection.
G.729
Average voice quality. The necessary bandwidth is less than or equal to 8 kbit/s
per voice connection.
To save additional bandwidth and transmission capacity, on VoIP connections
that use the G.729 codec you can suppress the transmission of voice packets in
pauses ("silence suppression"). Instead of the background noises in your envi-
ronment, your caller then hears a synthetic noise generated in the receiver
(option: Enable Annex B for codec G.729).
Please note
Observe the following for good voice quality:
u
When making calls using VoIP, avoid performing other Internet activities
(e.g., surfing the Internet).
u
Please note that voice delays can occur depending on the codec used and
the network capacity utilisation.
