Modify the Dialplan in the Line1 (or Line2) settings by adding <:520>
to the 7-digit section:
|<:520>[2-9]xxxxxx|
In this example,
520
is our local 7-digit area code.
(*xx|[3469]11|0|00|<:520>[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)
For maximum bandwidth savings, use g.729a
.
Otherwise, choose (the default) g.711u
(uncompressed) for best audio quality.
Also, be sure to set the RTP Packet Size
to 0.020
on the SIP tab.
