SIP Reg User Agent Name User-Agent name to be used in a REGISTER request. If
this is not specified, the <SIP User Agent Name> is
also used for the REGISTER request.
Defaults to blank.
SIP Accept Language Accept-Language header used. To access, click the
SIP tab, and fill in the SIP Accept Language field.
There is no default (this indicates IP phone does not
include this header). If empty, the header is not
included.
DTMF Relay MIME Type MIME Type used in a SIP INFO message to signal a
DTMF event. This field must match that of the Service
Provider.
Defaults to application/dtmf-relay.
Hook Flash MIME Type MIME Type used in a SIP INFO message to signal a
hook flash event.
The default is application/hook-flash.
Remove Last Reg Lets you remove the last registration before registering
a new one if the value is different. Select yes or no from
the drop-down menu.
Defaults to no.
Use Compact Header Lets you use compact SIP headers in outbound SIP
messages. Select yes or no from the drop-down menu.
If set to yes, the phone uses compact SIP headers in
outbound SIP messages. If set to no, the phone uses
normal SIP headers. If inbound SIP requests contain
compact headers, the phone reuses the same
compact headers when generating the response
regardless the settings of the <Use Compact Header>
parameter. If inbound SIP requests contain normal
headers, the phone substitutes those headers with
compact headers (if defined by RFC 261) if <Use
Compact Header> parameter is set to yes.
Default: no
