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.
