Defines
-
PJ_DNS_MAX_IP_IN_A_REC
Maximum number of IP addresses in DNS A response.
-
PJ_DNS_SRV_MAX_ADDR
Maximum server address entries per one SRV record
-
PJ_DNS_MAX_NAMES_IN_NAMETABLE
This constant specifies the maximum names to keep in the temporary name table when performing name compression scheme when duplicating DNS packet (the pj_dns_packet_dup() function).
Generally name compression is desired, since it saves some memory (see PJ_DNS_RESOLVER_RES_BUF_SIZE setting). However it comes at the expense of a little processing overhead to perform name scanning and also a little bit more stack usage (8 bytes per entry on 32bit platform).
Default: 16
-
PJ_DNS_RESOLVER_MAX_NS
Maximum numbers of DNS nameservers that can be configured in resolver.
-
PJ_DNS_RESOLVER_QUERY_RETRANSMIT_DELAY
Default retransmission delay, in miliseconds. The combination of retransmission delay and count determines the query timeout.
Default: 2000 (2 seconds, according to RFC 1035)
-
PJ_DNS_RESOLVER_QUERY_RETRANSMIT_COUNT
Maximum number of transmissions before timeout is declared for the query.
Default: 5
-
PJ_DNS_RESOLVER_MAX_TTL
Maximum life-time of DNS response in the resolver response cache, in seconds. If the value is zero, then DNS response caching will be disabled.
Default is 300 seconds (5 minutes).

-
PJ_DNS_RESOLVER_INVALID_TTL
The life-time of invalid DNS response in the resolver response cache. An invalid DNS response is a response which RCODE is non-zero and response without any answer section. These responses can be put in the cache too to minimize message round-trip.
Default: 60 (one minute).

-
PJ_DNS_RESOLVER_GOOD_NS_TTL
The interval on which nameservers which are known to be good to be probed again to determine whether they are still good. Note that this applies to both active nameserver (the one currently being used) and idle nameservers (good nameservers that are not currently selected). The probing to query the “goodness” of nameservers involves sending the same query to multiple servers, so it’s probably not a good idea to send this probing too often.
Default: 600 (ten minutes)

-
PJ_DNS_RESOLVER_BAD_NS_TTL
The interval on which nameservers which known to be bad to be probed again to determine whether it is still bad.
Default: 60 (one minute)

-
PJ_DNS_RESOLVER_MAX_UDP_SIZE
Maximum size of UDP packet. RFC 1035 states that maximum size of DNS packet carried over UDP is 512 bytes.
Default: 512 byes
-
PJ_DNS_RESOLVER_RES_BUF_SIZE
Size of memory pool allocated for each individual DNS response cache. This value here should be more or less the same as maximum UDP packet size (PJ_DNS_RESOLVER_MAX_UDP_SIZE), since the DNS replicator function (pj_dns_packet_dup()) is also capable of performing name compressions.
Default: 512
-
PJ_DNS_RESOLVER_TMP_BUF_SIZE
Size of temporary pool buffer for parsing DNS packets in resolver.
default: 4000
-
PJ_SCANNER_USE_BITWISE
Macro PJ_SCANNER_USE_BITWISE is defined and non-zero (by default yes) will enable the use of bitwise for character input specification (cis). This would save several kilobytes of .bss memory in the SIP parser.
-
PJSTUN_MAX_ATTR
Maximum number of attributes in the STUN packet (for the old STUN library).
Default: 16
-
PJ_STUN_MAX_ATTR
Maximum number of attributes in the STUN packet (for the new STUN library).
Default: 16
-
PJ_CRC32_HAS_TABLES
Specifies whether CRC32 algorithm should use the table based lookup table for faster calculation, at the expense of about 1KB table size on the executable. If zero, the CRC32 will use non-table based which is more than an order of magnitude slower.
Default: 1
-
PJ_HTTP_DEFAULT_TIMEOUT
Timeout value for HTTP request operation. The value is in ms. Default: 60000ms
-
PJ_CLI_POOL_SIZE
Initial pool size for CLI. Default: 1024 bytes
-
PJ_CLI_POOL_INC
Pool increment size for CLI. Default: 512 bytes
-
PJ_CLI_MAX_CMDBUF
Maximum length of command buffer. Default: 512
-
PJ_CLI_MAX_ARGS
Maximum command arguments. Default: 8
-
PJ_CLI_MAX_HINTS
Maximum number of hints. Default: 32
-
PJ_CLI_MAX_SHORTCUTS
Maximum short name version (shortcuts) for a command. Default: 4
-
PJ_CLI_CONSOLE_POOL_SIZE
Initial pool size for console CLI. Default: 256 bytes
-
PJ_CLI_CONSOLE_POOL_INC
Pool increment size for console CLI. Default: 256 bytes
-
PJ_CLI_TELNET_POOL_SIZE
Initial pool size for telnet CLI. Default: 1024 bytes
-
PJ_CLI_TELNET_POOL_INC
Pool increment size for telnet CLI. Default: 512 bytes
-
PJ_CLI_MAX_CHOICE_VAL
Maximum number of argument values of choice type. Default: 64
-
PJ_CLI_MAX_CMD_HISTORY
Maximum number of command history. Default: 16
-
PJ_DNS_MAX_IP_IN_A_REC
