Note

 

The network bandwidth necessary to send the encoded audio is typically 5~10% higher than the bit rate due 
to packetization overhead. For example, a two-way G.722 audio call at 64 Kbps consumes about 135 Kbps of 
network bandwidth. 

The Opus codec supports various audio bandwidths, defined as follows: 

Abbreviation 

Audio Bandwidth 

Sample Rate (Effective) 

NB (narrowband) 

4 kHz 

8 kHz 

MB (medium-band)

12 kHz 

WB (wideband)

16 kHz 

SWB (super-wideband)

FB (fullband)

48 kHz 

 

Note

 

The T40P/T40G/T23P/T23G/T21(P) E2/T19(P) E2 IP phones support using WB for Opus encoding; and using 
NB, MB, WB, SWB and FB for Opus decoding. 

The T54S/T52S/T48S/T46S/T42S/T41S/T27G IP phones support using WB (default) or NB for Opus encoding; 
and using NB, MB, WB, SWB and FB for Opus decoding.

 

The IP phones support up to two calls or a three-way conference when using Opus. 

The following table lists the audio codecs supported by each phone model:
