Redundancy settings
Redundancy - DNS query
VoIP providers provide SIP server redundancy for load balancing and service reliability. SIP serv-
ers can be identified by DNS using different queries:
A
SRV + A
Failover server
If Redundancy - DNS query = A
In case your provider supports a failover server you can enter the data here.
¤
Enable/disable the use of a failover server via the radio boxes next to Enable registration.
Registration server
¤
Enter the IP address or the (fully qualified) DNS name of the failover registration server.
SIP server port
¤
Enter the communication port used on the failover registrar.
Range: 1-65535; Default: 5060 (for UDP/TCP), 5061 (for TLS)
Network data of the service provider
Outbound proxy mode
The DECT IP multicell system allows you to configure an outbound proxy. Despite any other SIP
protocol rules, if activated (Always), the system will always send all outgoing requests towards
this outbound proxy. It can be an outbound proxy in the local network provided by the local net-
work provider or in the public network provided by the network/VoIP provider.
¤
Specify when the outbound proxy should be used.
Always:
Never:
If the further outbound proxy configuration is identical to the proxy and registrar configuration
it is useless and will be ignored.

Records just the specified IP addresses and the related port numbers.
Finds an available server port for the specified proxy and registration server. DNS
SRV allows a client to only have to know what type of service it is looking for instead
of the actual server.
All signalling and voice data sent by the system is sent to the outbound proxy.
The outbound proxy is not used.
The DHCP option 120 "sip server" sent by a SIP phone would internally overrule the
outbound proxy address and port setting. Outbound proxy mode is still and exclu-
sively in the hands of the local device administrator. By setting Outbound proxy
mode to Never, you can prevent any usage of DHCP option 120 by the DECT VoIP
phone. To allow for DHCP option 120, you should set Outbound proxy mode to
Always.
