3.5.2.5 Local UDP Port
The Local UDP Port defines the port, normally 5060, the LIP Phone will use to send and receive
SIP signalling packets. Particularly when behind a firewall, in some instances the normal port
may not be availabe and a different port can be defined.
To set the Local UDP Port:
1) Press the button. If the LCD Menu is locked, use the unlock procedure (refer to
Section 3.3 Lock/Unlock Configuration).
2) Press button, or move cursor to 2.SIP Configuration using the [Next]/[Prev] Softkeys,
and press the [ OK ] Softkey.
3) Press button, or move cursor to 7.Local UDP Port using the [Next]/[Prev] Softkeys,
and press the [ OK ] Softkey.
4) Input the Backup Proxy Port for the LIP-6812/LIP-6830 using the Dial pad.
5) Press the [ OK ] Softkey to save your Configuration.
6) Press the button to exit from the menu.
Changing the Local UDP Port requires a reboot of the LIP-6812/LIP-6830; when you
leave the menu, you will receive a Reboot notice.
3.5.2.6 RTP Start Port
When a SIP call is established, digitized voice signals are sent and received in Real-Time
Protocol (RTP) packets. The port used for RTP packets is usually 23000, but a different port
may be defined.
To assign an RTP port:
1) Press the button. If the LCD Menu is locked, use the unlock procedure (refer to
Section 3.3 Lock/Unlock Configuration).
2) Press button, or move cursor to 2.SIP Configuration using the [Next]/[Prev] Softkeys,
and press the [ OK ] Softkey.
