Time Out – Set the time out for the call forwarding. The

default setting is 30 sec.

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.
