Ring Port Set Phone 1 and/or Phone 2 as the default ring port(s) for
this SIP account.
Ring Pattern Choose a ring tone type for the VoIP phone call.
Prefer Codec Select one of five 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.
Single Codec – If the box is checked, only the selected
Codec will be applied.
Packet Size The amount of data contained in a single packet. The
default value is 20 ms, which means the data packet will
contain 20 ms voice information.
Voice Active Detector This function can detect if the voice on both sides is active
or not. If not, the router will do something to save the
bandwidth for other using. Click On to invoke this function;
click off to close the function.
After finishing all the settings here, please click OK to save the configuration.
