Local UDP Port
The Local UDP Port defines the port, normally 5060, that the phone uses to send and receive SIP signaling
packets. In some instances, particularly when behind a firewall, port 5060 may already be in use or
problematic with SIP aware routers.
To change the Local UDP Port:
•
Press the
button, then select 2. SIP Configuration, then 6. Local UDP Port.
•
Input the Local UDP Port using the dial pad and press the OK
softkey to save your entry.
Changing the Local UDP Port requires a reboot of the IP phone.
RTP Start Port
When a SIP call is established, Real-Time Transport Protocol (RTP) packets transport media (voice). The
default port used for RTP packets is 23000.
To change an RTP Start Port:
•
Press the
button, then select 2. SIP Configuration, then 7. RTP Start Port.
•
Input the RTP Start Port using the dial pad and press the OK softkey
to save your entry.
Changing the RTP Start Port requires a reboot of the IP phone.
Proxy Registration
If Proxy Registration is set to Yes, the phone will register with the appropriate SIP or proxy server upon
initial power-up, during a reboot and at periodic intervals based on the timer defined by the server.
To enable Proxy Registration:
•
Press the
button, then select 2. SIP Configuration, then 8. Proxy Registration.
•
To enable registration, press the Yes softkey. To disable SIP
registration, press the No softkey.
