Enable or disable suppress
subscription during
transfer. When transferring
a SIP call, the SIP REFER
process automatically
establishes a temporary
event subscription to notify
the party initiating the
transfer about the
receiver's status in handling
the REFER. In some cases
these event subscriptions
and notifications are not
needed, such as when
forking is not used. Enable
this option to suppress the
automatic event
subscriptions when
transferring calls. (See IETF
RFC 4488.)
Use compact SIP message
format. The SIP protocol
specifies that header field
names can be in the full
name form or in the
abbreviated form.
Abbreviated form is useful
when messages might be
too large to be carried on
the available transport, for
example when exceeding
UDP's Maximum
Transmission Unit (MTU).
Enable this option to
encode SIP headers in their
short forms to reduce size.
By default, the option is not
enabled and SIP headers in
outgoing messages will be
encoded in their full
names. (See SIP protocol
standard, IETF RFC 3261.)
