STUN refresh time
Enter the time intervals at which the phone should repeat the registration with
the STUN server. The repeat is required so that the entry of the phone in the
tables of the STUN server is retained. The repeat is carried out for all activated
VoIP phone numbers.
Ask your VoIP provider for the
STUN refresh time
.
The default is 240 seconds.
If you enter 0 seconds, the registration will not be repeated periodically.
NAT refresh time
Specify the intervals at which you want the phone to update its entry in the
NAT routing table. Specify an interval in seconds that is a little shorter than the
NAT session timeout.
You should not need to change the preconfigured value for the
NAT refresh time
.
Outbound proxy mode
Specify when the outbound proxy should be used.
Always
All signaling and voice data sent by the phone is sent to the outbound proxy.
Auto
Data sent by the phone is only sent to the outbound proxy when the phone
is connected to a router with symmetric NAT or blocking firewall. If the
phone is behind an asymmetric NAT, the STUN server is used.
If you have set
STUN enabled
=
No
or have not entered a STUN server, the out-
bound proxy is always used.
Never
The outbound proxy is not used.
If you do not make an entry in the
Outbound proxy
field, the phone behaves
independently of the selected mode, as with
Never
.
Outbound proxy
Enter the (fully qualified) DNS name or the IP address of your provider's out-
bound proxy (maximum 74 characters).
Outbound proxy port
Enter the number of the communication port used by the outbound proxy.
The default port is 5060.
Please note
With many providers, the outbound proxy is identical to the SIP proxy.
