your router.
Manual

external IP address as the NAT transversal support.

solution, you can choose this option.
Call Forwarding
There are four options for you to choose.
Disable
is to close
call forwarding function.
Always
means all the incoming calls
will be forwarded into SIP URL without any reason.
Busy
means the incoming calls will be forwarded into SIP URL only
when the local system is busy.
No Answer
means if the
incoming calls do not receive any response, they will be
forwarded to the SIP URL by the time out.
SIP URL
– Type in the SIP URL (e.g., aaa@draytel.org or
abc@iptel.org) as the site for call forwarded.
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.
