Configuring the phone via the Web configurator
Proxy Port
Enter the number of the communication port that the SIP proxy uses to send
and receive signaling data (SIP port).
Port 5060 is used by most VoIP providers.
Use Outbound Proxy
Define whether or not the outbound proxy should be set. If this checkbox is
activated, all signaling and voice data sent by the phone will be sent to the
outbound proxy. Only use the outbound proxy if instructed to do so by your
provider.
Outbound Proxy Address (only if Use Outbound Proxy is activated)
Enter the DNS name or the IP address of your provider's outbound proxy.
Outbound Proxy Port (only if Use Outbound Proxy is activated)
Enter the number of the communication port used by the outbound proxy.
The default port is 5060.
Call Waiting
If this function is activated you will hear a knocking tone if you receive an
incoming call during another call.
NAT traversal
If your phone is connected to a router with NAT (Network Address Translation)
and/or a firewall, you must select some settings in this area so that your phone
can be reached from the Internet (i.e., can be addressed).
Through NAT, the IP addresses of subscribers in the LAN are concealed behind
the public IP address of the router.
Please note
With many providers, the outbound proxy is identical to the SIP proxy.
Please note
