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
other activates that demand memory allocation.

General Pool Num of Pages: The pages number of General

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: 500ms) **

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,
retransmission continue but at an interval of T2. (Default
Value: 4000ms) **

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) **

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)**

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(Default Value: 10000ms).**

Processing Queue Size: the maximum length of the

processing queue which holds events such as network
events.
