HP-UX C SIP Stack Programmer's Guide (Novembery 2007)

Configuration 395
Configuration Parameters
Remarks:
 Group B parameter: maxTransaction = maxCallLegs +
maxSubscriptions
 If maxCallLeg = 0, then maxTransactions = 10 +
maxSubscriptions
maxRegClients
The maximum number of register-clients the SIP Stack allocates. You should set
this value to the maximum number of Register-Clients you expect the SIP Stack
to handle simultaneously.
Default Value: 2
Remarks: Group A parameter
maxTransmitters
The number of Transmitters that the SIP Stack allocates. You should set this
value to the maximum number of transmitters you expect the SIP Stack to
handle simultaneously. A transmitter is used for sending a message that is not
related to transactions such as ACK on 2xx for forked INVITE, or responses for
messages with syntax errors that fail to create a transaction. The application may
also use transmitter for sending stand-alone messages.
Note Each SIP Stack transaction also uses a transmitter but the transmitters for
the transactions are allocated by the SIP Stack automatically and you do not have
to add them to the maxTransmitters parameters.
Default value: –1
Remarks:
 Group B parameter: maxTransmitters = 10 + maxCallLegs +
maxTransactions
 If forking is enabled, the value will be increased by
maxCallLegs/2.
MEMORY POOL
A
LLOCATION
A memory pool consists of a set of memory pages used by the SIP Stack for
storage. The SIP Stack uses three different pools:
 Message Pool
 General Pool
