Field Setting
NAT keepalive (Optional) If enabled, the Spectralink IP-DECT/Virtual IP-DECT Server
sends UDP packets periodically to ensure that NAT trans-
lation continues. If not enabled, the port may be closed down
for security reasons (as a consequence call will be dropped
or disrupted).
Possible values: Disabled, CRLF (rfc5626) or SIP
OPTIONS (rfc3261).
Default value:CRLF (RFC 5626)
Note: CRLF is only used for TCP transport. SIP OPTIONS
is used for both UDP and TCP transports. If using UDP trans-
port, then NAT keepalive is disabled unless you select SIP
OPTIONS.
NAT keepalive interval(sec)
(Optional)
If NAT keepalive is enabled, specify the interval at which NAT
keepalive packets must be sent.
Possible values: 10, 20 or 30 sec
Default value: 30 sec
Send Hold before REFER
(Optional)
If enabled, all calls are put on hold before initiating a call trans-
fer using a REFER message. Some call control platforms
require this to be disabled, otherwise the transfer target may
stay on hold after a transfer has completed.
Default value: Enabled
Convert SIP URI to phone num-
ber (Optional)
If enabled, the Spectralink IP-DECT/Virtual IP-DECT Server
converts the callers SIP URI received from the PBX to a
phone number, e.g. “SIP:1234@example.com” to “1234”.
The phone number is then displayed in a DECT handset as
the caller ID instead of the SIP URI.
Note: Conversion of SIP URIs makes the Call back feature
unusable for users on a different domain.
Default value: Enabled
SIP Configuration - Proxies
Proxies (Optional) Priority: The priority for using this proxy.
Possible Value 1-4.
Weight: The weight for using this proxy if more proxies have
the same priority.
Possible value 1 - 65.000 higher weight gives priority.
Default value: 100
URI: The URI or IP address of the proxy
