Ring Port Set Phone or DECT as the default ring port for this SIP
account. The ports you can set are different based on the
model you have.
Ring Pattern Choose a ring tone type for the VoIP phone call.
Prefer Codec Select one of the codecs as the default for your VoIP calls. The
codec used for each call will be negotiated with the peer party
before each session, and so may not be your default choice.
The default codec is G.729A/B; it occupies little bandwidth
while maintaining good voice quality.
If your upstream speed is only 64Kbps, do not use G.711
codec. It is better for you to have at least 256Kbps upstream if
you would like to use G.711.
