Use Compact Header
Lets you use compact SIP headers in outbound
SIP messages. Select yes or no from the drop-
down list. If set to yes, the SRP uses compact SIP
headers in outbound SIP messages. If set to no,
the SRP uses normal SIP headers. If inbound SIP
requests contain compact headers, the SRP
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 SRP
substitutes those headers with compact headers
(if defined by RFC 261) if Use Compact Header
parameter is set to yes.
The default is no.
Escape Display Name
Lets you keep the Display Name private. Select
yes if you want the SRP 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.
The default is no.
RFC 2543 Call Hold
Configures the type of call hold: a:sendonly or
0.0.0.0. The default is no; do not use the 0.0.0.0
syntax in a HOLD SDP; use the a:sendonly syntax.
Mark All AVT Packets
If set to yes, all AVT tone packets (encoded for
redundancy) have the marker bit set. If set to no,
only the first packet has the marker bit set for each
DTMF event.
The default is yes.
