These configuration properties may be specified when creating or updating an RA entity (createRAEntity and updateRAEntityConfigProperties management commands).

Name Type Default Value Reconfigurable while active? Description 
config-profile

String

None, a value must be supplied on RA entity creation.

✅

The ProfileID of the Configuration Profile that will be used to configure this RA entity. The string must be in the form "table-name/profile-name".

 
WorkerPoolSize

Integer

 
4

❌

Number of worker threads the SIP Servlet RA will use to process incoming messages. If zero, the RA will process messages in the receiving I/O thread. Otherwise, messages will be handed off to the pool so they can be processed concurrently.

 
WorkerQueueSize

Integer

 
500

❌

Queue size for the worker thread pool. If the queue fills, then the RA will drop packets (UDP) or temporarily suspend socket reads (TCP).

 
TCPIOThreads

Integer

 
1

❌

Number of threads for handling TCP I/O. TCP connections will be divided between the I/O threads.

 
AllowLoopbackSend

Boolean

 
false

❌

Controls whether the RA may send SIP requests to its own addresses. Disabled by default to prevent accidental loops.

 
Automatic100TryingSupport

Boolean

 
true

✅

If enabled, the RA will automatically generate 100 Trying responses for INVITEs.

 
OffsetPorts

Boolean

 
false

❌

Required if running multiple cluster nodes on the same host. If true, the RA will automatically add an offset to each SIP network interface port, so that each RA instance gets a different port number. See PortOffset below.

 
PortOffset

Integer

 
0

❌

Required when running multiple cluster nodes on the same host. If OffsetPorts is enabled, a network interface’s port will be calculated as Port + (NodeID - PortOffset). Typically the PortOffset value used is the lowest NodeID in the cluster. So if the network interface Port is 5060, and the lowest NodeID is 101, and the cluster has nodes 101, 102 and 103, the actual ports used will be 5060, 5061 and 5062 respectively.

 
fiber-pool.core-pool-size

Integer

 
2

✅

The RA’s fiber pool is a thread pool used for ordering execution of tasks within the SIP Servlet implementation. The core pool size is the minimum size of this thread pool.

 
fiber-pool.max-pool-size

Integer

 
8

✅

The maximum number of threads that may be used by the fiber pool.

 
fiber-pool.queue-size

Integer

 
500

✅

The maximum size of the fiber pool’s input queue.

 
RFC3263:failover_enabled

Boolean

 
false

❌

Specifies whether to use RFC 3263 Failover & Load Balancing. By default this is disabled, to match existing behaviour. If enabled, the RA uses RFC 3263 DNS procedures to find possible servers and automatically fails over to backup servers where available. If multiple servers are found in DNS, they are sorted and tried according to their SRV priority and weight as per RFC 2782. If disabled, the DNS procedures are still used to find server addresses, but only the first address is used.

 
RFC3263:failover_timer

Long

 
10000

❌

Specifies the duration of the failover timer in milliseconds. If RFC 3263 failover is enabled and this timer expires before any responses were received, the RA treats this as a transport error and tries sending the request to the next available server. This timer should be set to a value smaller than the default Timer B and Timer F timers (32s) so that failures can be detected promptly. A value of zero or less disables this timer.

 
RFC3263:blacklist_timer

Long

 
300000

❌

The duration in milliseconds for which a server will be blacklisted after a failure is detected. This avoids the RA trying to use the server immediately after a failure when it is most likely just going to fail again. After this time has passed the failed server may be tried again on subsequent client transactions. If a server specifies a Retry-After duration in a 503 response, that value will be used instead.

SSL/TLS Properties

These properties are only used if a network interface is configured to use the TLS transport.

Name Type Default Value Reconfigurable while active? Description 
Keystore

String

 
${rhino.dir.base}/
sipservlet-data/
sipservlet.keystore

❌

The name of a keystore file used to store private key material.

 
KeystoreType

String

 
jks

❌

The type of keystore implementation.

 
KeystorePassword

String

 
Empty string (no password).

❌

Password to unlock the keystore.

 
Truststore

String

 
${rhino.dir.base}/
sipservlet-data/
sipservlet.keystore

❌

The name of a truststore file containing trusted CA certificates. May be same as Keystore.

 
TruststoreType

String

 
jks

❌

 
TruststorePassword

String

Empty string
(no password).

❌

Password to unlock the truststore.

 
CRLURL

String

None.

❌

The location of a certificate revocation list.

 
CRLRefreshTimeout

Integer

 
86400

❌

The certificate revocation list refresh timeout, in seconds.

 
CRLLoadFailureRetryTimeout

Integer

 
900

❌

The certificate revocation list load failure timeout, in seconds.

 
CRLNoCRLLoadFailure
RetryTimeout

Integer

 
60

❌

The certificate revocation list load failure retry timeout, in seconds.

 
ClientAuthentication

String

 
NEED

❌

Indicate whether clients need to be authenticated against certificates in the truststore, must be one of NEED, WANT or NONE:

  • NEED - client authentication is required.

  • WANT - client authentication is requested but not required.

  • NONE - no client authentication is required.

 
EnabledCipherSuites

String

 




❌






Comma-separated list of cipher suites to enable on all TLS sockets. If empty, the JVM’s default cipher suites will be used. See
Java SE 6 cipher suites.
