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
Escape Display Name Lets you keep the Display Name private. Select yes if
you want the IP phone to enclose the string (configured
in the Display Name) in a pair of double quotes for
outbound SIP messages. Any occurrences of or \ in the
string is escaped with \ and \\ inside the pair of double
quotes. Otherwise, select no.
Defaults to yes.

RFC 2543 Call Hold If set to yes, unit will include c=0.0.0.0 syntax in SDP
when sending a SIP re-INVITE to the peer to hold the
call. If set to no, unit will not include the c=0.0.0.0 syntax
in the SDP. The unit will always include a=sendonly
syntax in the SDP in either case.
