A
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 SPA9000 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
