This guide details all configurations that are available within Alpaca. All configurations can be used in the application-prod.yml file located in the /etc/alpaca/server.

YAML (YAML Ain't Markup Language)

All Alpaca configurations are in the YAML (.yml) format.

Basic Rules

  • YAML is case sensitive.
  • YAML does not allow the use of tabs. Spaces are used instead as tabs are not universally supported.
  • A dictionary is represented in a simple key: value form (the colon must be followed by a space):

              announcementRepositoryUsername: "BoNjOuRlEsAmIs049"
              announcementRepositoryPassword: "viveLEROILouis14"
              htmlEncodeExports: true
  • All members of a list are lines beginning at the same indentation level starting with a - (a dash and a space):

        - cluster: Production
          fileRepo: ProfileServer
          username: fileadmin
          password: P@ssw0rd
        - cluster: Lab
          fileRepo: ProfileServer
          username: fileadmin
          password: P@ssw0rd
  • Comments are denoted by #.

      # Alpaca Configuration
          # Migration Configuration
            announcementRepositoryUsername: "BoNjOuRlEsAmIs049"
            announcementRepositoryPassword: "viveLEROILouis14"
            htmlEncodeExports: true

Alpaca (alpaca)

alpaca is the root header for Alpaca Server related configurations.

Audit Logs (auditLogs)

Audit log configurations control what happens when Alpaca is parsing audit logs from BroadWorks.

  • fireAlertsForTasks: If disabled, Alpaca will not fire alerts for audit logs that are the result of a task that Alpaca started, i.e. Enterprise Migration.
  • retentionDays: The number of days audit logs are retained for. -1 will cause the audit logs to be retained indefinitely.
  • skipReads: If set to true, audit logs that are "reads" will be ignored by Alpaca.

Client (client)

Client configurations affect items that are seen on the Alpaca Server web interface.

  • hideAuthenticationReset: If set to true, the SIP Authentication Reset action will not be hidden from Users.

Device Name Config (deviceNameConfig)

Configuration to determine Device naming during a Device Migration.

  • deviceNameTemplate: Default template used for renaming the device. This is used if a template value is not supplied for a matched entry from the template list. Valid template replacement values are:
    • {deviceName} - The device's current name.
    • {deviceType} - The device's type.
    • {mac} - The device's MAC address.
  • templateList : Templates for Device's with potential subtypes.
    • name : Name of the templated DeviceType. This must match the name of a DeviceType in BroadWorks.
    • template : Default template for this type. This value will determine the Device's final name if a subtype is not selected.
    • subtypes : A map of Device Types to Device Type templates. The Device Type keys will appear in the Alpaca client under the selected template name. The template value will determine the Device's final name.

User Replace (userReplace)

Configurations used for the User Replace task.

  • userIdMask - The title that will be used for the user id field in the User Replace wizard.
  • userIdPattern - The regex pattern that the new user id for User Replace must match.

CommuniGate (communigate)

Client configurations used for the CommuniGate Voicemail tool.

  • communigateClusterNickname - The nickname of the BroadWorks cluster to associate Communigate with.
  • communigateServiceProviderId - This is the Service Provider ID that Users will be created within.
  • communigateLoginDisabledEmail - Where login disabled assistance requests will be sent.
  • communigateVoicemailDnLength - The required number length for User creation. This is validated by the client.

File Store (fileStore)

Configurations that deal with the Alpaca Filestore.

  • cleanupInterval: The number of days between file store cleanups.
  • location: The absolute or relative location on the filesystem where exported files will be stored.

Mail (mail)

Configurations for sending emails from Alpaca.

  • baseUrl - The URL of the Alpaca server that the emails will be sent from.
  • from - The email address to send emails from.

Migration (migration)

Configurations used for performing various migrations within Alpaca.

  • announcementRepositoryUsername: The username to retrieve voice portal audio and video files from for migration procedures.
  • announcementRepositoryPassword: The password to retrieve voice portal audio and video files from for migration procedures.
  • authenticationPasswordChangeable: When randomizing a user's authentication password, the user's access device type must match the provided regular expression.
  • authenticationUsernameChangeable: When randomizing a user's authentication username, the user's access device type must match the provided regular expression.
  • blfCachingEnabled: When BLF caching is enabled, Alpaca will parse through all BLF entries and keep an updated database of monitoring users. This can cause startup to take a little longer but it will improve the speed of migrations.
  • deviceFileMigrationRuleList: Migration file rules consist of device types matched to the files that should be migrated with the device. There can be any number of file rules that specify the desired files to be migrated. If no rules are provided, no device files will be migrated during any type of migration.
  • deviceFileMigrationRuleList/deviceTypeRegex: This defines the file rule device type, as specified by regular expression.
  • deviceFileMigrationRuleList/fileRegexes: Any number of files can be specified by exact name.
  • deviceRebootDelayMillis: The delay in milliseconds between rebooting the device and performing the migration procedure.
  • htmlEncodeExports: When performing an export, special characters will be escaped if this option is turned on. Characters include <, >, &, =, and '.
  • ignoreLinePortTransforming: Only applies to line ports with the source default domain. If set to true, line ports with the source default domain, will not have their domain transformed to the destination default domain.
  • updateExpiredConferenceSchedules: If true, during a migration, expired Meet Me Conferences will be updated to the current time. Otherwise, the conference will not be migrated.
  • userDeletionDuringGroupDestroyThreshold: If a Group has more users than the threshold, each user will be individually deleted instead of being deleted as a part of the Group delete request.
  • ignoreNSSyncError: Configuration that will ignore an NS SYNC error returned from BroadWorks during a VoiceVPN Get Request call.

Security (security)

Configurations that can be used to make Alpaca more or less secure.

  • allowRegistation - If true, Users will be able to register via the registration page, otherwise they will have to be manually added by an admin.
  • rememberMe.key - A unique key used for remember-me tokens

Broadworks (broadworks)

broadworks is the root header for Alpaca Library related configurations.

  • asynchronousTimeoutMillis: Timeout for asynchronous calls.
  • autoFireMillis: When using a RequestBundler this timeout controls how long to wait before firing a request with less than 15 entries.
  • connectionReconnectAttempts: How many times to attempt a reconnect to BroadWorks once a connection is lost.
  • connectionReconnectDelayMillis: How long after a connection lost to attempt to reconnect.
  • connectionTimeoutMillis: How long before an un-answered request is deemed timed out.
  • encoding: The encoding to use for the outgoing and incoming parsing of BroadWorks messages.
  • maxRequestsPerSecond: The maximum number of requests to send per second through a single BroadWorksServer object. This is a blocking operation that will limit the overall speed of the code if attempting to perform too many operations per second.
  • maxRetriesForSystemError: The number of times to retry a request if it comes back as a System Error.
  • numberOfSocketsPerServer: How many sockets will be opened per BroadWorksServer connection.
  • sslPermissive: Whether to disable SNIExtension and use a universal trust strategy for SSL.
  • synchronousTimeoutMillis: Timeout for synchronous calls.

  • cluster: The nickname of the cluster configured in Alpaca.
  • file-repo: The file repository name in BroadWorks.
  • password: The password of the file repository admin.
  • username: The username of the file repository admin.

  • frameworkAddress: The CommuniGate server to connect to.
  • api-key: The api key provided by CommuniGate.
  • domain: The domain used for CommuniGate.

Spring (spring)

MongoDB (data.mongo)

The MongoDB configuration can be put in the data portion of your application-prod.yaml configuration file.

  • database - The name of the database to use for Alpaca. This should always be alpaca.
  • uri - The address of the local Mongo installation. This is typically mongodb://localhost:27017.

Email (mail)

  • host - The server to connect to.
  • password - The password for the email account that is being used.
  • port - The port to connect to. Defaults to 25.
  • protocol - The protocol to use to send the email, i.e. SMTP, POP3, IMAP.
  • properties.mail.smtp - Mail properties if using SMTP.
    • auth - If true, attempt to authenticate the user using the AUTH command. Defaults to false.
    • - If set to "*", all hosts are trusted. If set to a whitespace separated list of hosts, those hosts are trusted. Otherwise, trust depends on the certificate the server presents.
    • starttls.enable - If true, enables the use of the STARTTLS command (if supported by the server) to switch the connection to a TLS-protected connection before issuing any login commands. Note that an appropriate trust store must be configured so that the client will trust the server's certificate. Defaults to false.
  • username - The email account to use to send emails from.

File Upload (servlet.multipart)

  • location: Intermediate location of uploaded files.
  • max-file-size: Max file size. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively. Defaulted to 1000MB. Setting to -1, makes the file size unlimited.
  • max-request-size: Max request size. Values can use the suffixes "MB" or "KB" to indicate megabytes or kilobytes, respectively. Defaulted to 1000MB. Setting to -1, makes the request size unlimited.

SSL Configuration

To configure Alpaca to run via SSL, start by enabling the https profile. See Profile Configuration. Once enabled, the application-https.yaml needs to be configured.

Generating a Key Store

To enable SSL you need a valid Java keystore configured. This first requires a valid certificate.

After the certificate has been created, use openssl to create a keystore file.

# openssl pkcs12 -export -in fullchain.pem -inkey privkey.pem -out keystore.pkcs12

To verify that the certificate was correctly imported:

# keytool -list -keystore config/keystore.pkcs12 -storetype pkcs12 -alias 1

Now the keystore can be copied to the Alpaca configuration directory for usage.

  1. # cp keystore.pkcs12 /opt/alpaca/config/
  2. # chown alpaca:alpaca /opt/alpaca/config/config/keystore.pkcs12

Configurations (server.ssl)

These configurations assume that necessary keys, key stores, and certificates have already been generated.

  • ciphers - Supported SSL ciphers.
  • keyAlias - Alias that identifies the key in the key store.
  • keyPassword - Password used to access the key in the key store.
  • keyStore - Path to the key store that holds the SSL certificate (typically a jks or pem file).
  • keyStorePassword - Password used to access the key store.
  • keyStoreType - Type of the key store.
  • protocol - SSL protocol to use.


  • prod - This is the primary configuration for production.
  • https - Enables ssl. See the SSL Configuration.

Profile selection can be done in the alpaca-server script using the --profiles option followed by a comma-separated list of profiles. They can be configured on service startup in the alpaca service script using the PROFILES field.

Configure AlpacaStore Cleanup Process

Alpaca is configured to remove older JSON files from migrations and exports after 90 days by default. If the default needs to be changed, review the following steps.

  1. In the application-prod.yml configuration file, locate the file-store configuration under alpaca.

  2. Change the cleanup-interval value to the desired number of days to retain files within the configured location.
