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
