protocol is used, general requests are retransmitted at an interval which
starts at T1 and doubles until reaches T2. If a provisional response is
received, retransmission continue but at an interval of T2. (Default Value:
4000ms) **
• RetransmissionT4 (msec.): T4 represents the amount of time the network
takes to clear message between client and server transactions as defined
in RFC3261. For example, when working with an unreliable transport
protocol, T4 determines the time that UAS waits after receiving an ACK
message and before terminating the transaction. (Default Value: 5000) **
• Cancel General No Response Timer (msec.): When sending a CANCEL
request on a General transaction, the User Agent waits cancel
GeneralNoResponseTimer milliseconds before timeout termination if there
is no response for the cancelled transaction(Default Value: 10000ms).**
• General Request Timeout Timer (msec.): After sending a General request,
the User Agent waits for a final response generalRequestTimeoutTimer
milliseconds before timeout termination (in this time the User Agent
retransmits the request every T1, 2*T1,…T2,…milliseconds)**
• Proxy 2xx Rcvd Timer (msec.): A successful client INVITE transaction of a
Proxy server includes only the INVITE request and the 2xx response. (The
ACK is not part of the transaction.)After receiving the 2xx response, the
Proxy will wait proxy2xxRcvdTimer before the transaction terminates.
(default: 10000 ms)**
• Proxy 2xx Sent Timer (msec.): A successful server INVITE transaction of a
Proxy server includes only the INVITE request and the 2xx response. (The
ACK is not part of the transaction).After sending the 2xx response the
Proxy will wait proxy2xxSentTimer before the transaction will terminate.
(default: 8000 ms)**
• Use Domain for Auth: Send “Domain” in 401 or 407 for authentication or not
• General Guard Time: The general guard time for internal purpose only
• Nonce Valid Period: The max valid time for a nonce. Once time out,
SIPPBX 6200 will issue a new nonce for authentication. Set it to 0 will
cause SIPPBX 6200 to generate new nonce for each call or register
• Valid Period Auth Mode: During the nonce valid period, does a subscriber
need send response on the “register”/“invite” message or not
- None: User agent doesn’t need send MD response in register invite
message
- MD: User agent should send MD response over the current nonce. Or a
new nonce will be send by SIPPBX 6200
• Message Pool Page Size: Used to hold and process all incoming and
outgoing in the form of encoded message or message objects. It is
recommended that you configuration the page size to the average
message size your system is expected to manage.
• General Pool Page Size: Used by SIP Stack objects, such as call-legs and
transactions, to store the internal fields. For example, the call-leg object will
store the To, Form and Call-ID headers and the local and remote contact
addresses on the general pool pages. The general pool is also used for
