that the ATA does not include this header) If empty, the header is
not included.

event.

Remove Last Reg Determines whether or not the ATA removes the last registration
before submitting a new one, if the value is different. Select yes to
remove the last registration, or select no to omit this step.
Default setting: no
Use Compact Header Determines whether or not the ATA uses compact SIP headers in
outbound SIP messages. Select yes or no from the drop-down list.
Select yes to use compact SIP headers in outbound SIP messages.
Select no to use normal SIP headers. If inbound SIP requests
contain compact headers, the ATA 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 ATA substitutes those headers with compact
headers (if defined by RFC 261) if Use Compact Header parameter
is set to yes.
Default setting: no
Escape Display
Name
Determines whether or not the Display Name is private. Select yes
if you want the ATA to enclose the string (configured in the
Display Name) in a pair of double quotes for outbound SIP
messages.
If the display name includes " or \, these will be escaped
to \" and \\ within the double quotes. Otherwise, select no.
Default setting: no
RFC 2543 Call Hold Configures the type of call hold: a:sendonly or 0.0.0.0. Do not use
the 0.0.0.0 syntax in a HOLD SDP; use the a:sendonly syntax.
