Enable 100rel The use of the PRACK (Provisional Acknowledgment) method enables reliability to
be offered to SIP provisional responses (1xx series). This is very important if PSTN
inter-networking is to be supported. A user’s request to use reliable provisional
responses is invoked by the 100rel tag which is appended to the value of the
required header of initial signalling messages.
Send
Anonymous If this parameter is set to “Yes”, the “From” header in outgoing INVITE message will
be set to anonymous, essentially blocking the Caller ID from displaying.
