Parameter Description:
UDP Port: The local UDP port on which the SIP Stack listens.
Reliable Provision (100rel): Requited PRACK or not (100rel)
Max Call Leg: The maximum number of call-legs the SIP Stack allocates.
You should set this value to the maximum number of call you expect the
SIP Stack to handle simultaneously.
Max Transaction: The maximum number of transactions the SIP Stack
allocates. You should set this value to the maximum number of call you
expect the SIP Stack to handle simultaneously.
Max Register Client: The maximum number of Register-Clients the SIP
Stack allocates. You should set this value to the maximum number of call
you expect the SIP Stack to handle simultaneously.
Send Receive Buffer Size: Set the size of message buffer. The buffer used
by SIP Stack for receiving and sending SIP messages.
Reject Unsupported Extension: Yes or No
Message Pool Page Size: Used to hold and process all incoming and
outgoing message in the coming of encoded messages or message objects.
It is recommended that you configure the page size to the average
message size your system is expected to message.
General Pool Page Size: Used by SIP Stack objects, such as call-legs and
transaction, to store the internal fields. For example, the call-legs object will
store the going, coming and Call-ID headers and the local and the remote
contact addresses on the general pool pages. The general pool is also used
from other activities that demand memory allocation.
Application Pool Page Size: The size of page in the application pool.
Retransmission T1: T1 determines several timers as defined in RFC3261.
For example, when an unreliable transport protocol is used, a Client Invite
transaction retransmits requests at an interval that start at T1 seconds and
doubles after every retransmission. A Client General transaction
retransmits requests at an interval that starts at T1 and doubles until it
reaches T2. (Default Value: 500)
Retransmission T2: Determines the maximum retransmission interval as
defined in RFC3261. For example, when an unreliable transport 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,
IP Centrex 6850 20
Welltech Computer Co., Ltd.
retransmission continue but at an interval of T2. (Default Value: 4000)
Retransmission T4: 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)
Invite Linger Timer: After sending an ACK for an INVITE final response, a
client cannot be sure that the server has received the ACK message; the
client should be able to retransmit the ACK upon receiving retransmissions
of the final response for inviteLingerTimer milliseconds.
General Linger Timer: After a server sends a final response, the server
cannot be sure that the client has received the response message. The
server should be able to retransmit the response upon receiving
retransmissions of the request for generalLingerTimer milliseconds.
(Default Value: 32000)
Provisional Timer: When a client receives a provisional response, it
continues to retransmit the request, but with an interval of provisionalTimer
milliseconds.
Cancel General No Response Timer: When sending a CANCEL request on
a General transaction, the User Agent waits
cancelGeneralNoResponseTimer milliseconds before timeout termination if
there is no response for the cancelled transaction.
Cancel Invite No Response Timer: When sending a CANCEL request on a
Invite transaction, the User Agent waits cancelInviteNoResponseTimer
milliseconds before timeout termination if there is no response for the
cancelled transaction.
General Request Timeout Timer: 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)
Send 487 When Recv CANCEL: When receive CANCEL form remote site,
send “487 Request canceled”or not
