in the field for dialing automatically when you pick up the

the limited time that you set in this field, if there is no
response, the connecting call will be closed automatically.

correction.
Call Waiting - Check this box to invoke this function. A
notice sound will appear to tell the user new phone call is
waiting for your response. Click hook flash to pick up the
waiting phone call.
Call Transfer - Check this box to invoke this function.
Click hook flash to initiate another phone call. When the
phone call connection succeeds, hang up the phone. The
other two sides can communicate, then.
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 the 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.
