Try a specific VOIP Codec
A VoIP codec is a technology that determines the audio quality, bandwidth, and compression of VOIP
phone calls. Instead of using the default codecs you can force TopView and the Yeastar to use a specific
codec.
Default Yeastar Codecs:
Users report the most success with the
“u
-
Law”/PCMU/G.711”
codec with the non-LTE version of the
TG200.
Yeastar TG200:
•
Gateway > VOIP Settings > SIP Settings > Codecs
•
Allowed codecs: add u-law if it is not in the
“
Allowed Codecs
”
list
•
Remove any other
“
Allowed Codecs
”
•
Save and Apply settings
TopView Configurator
•
Voice notification settings > General
•
Click [Set call codecs..]
•
Select “Use custom codecs”
•
Check the PCMU (G7.11) codec
