Prolog information
LDAP based call routing feature routes the SIP INVITE message from a SIP trunk in an enterprise network with multiple SIP call servers.
This feature works in the following sequence:
  • Queries the Lightweight Directory Access Protocol (LDAP) server for user data.
  • Avaya SBC uses that user data to route incoming calls from a SIP trunk within the enterprise network.
  • On receiving SIP INVITE from SIP trunk, Avaya SBC initiates an LDAP query towards LDAP server.
  • On receiving the query response from LDAP server, Avaya SBC selects next hop based on the configured routing profiles.
The communication of Avaya SBC and LDAP server supports:
  • IPv4 and IPv6 addresses.
  • Management interface.
  • Ability to communicate with primary and alternate LDAP server. If the primary LDAP server is non-functional, then communication continues with the alternate server.
  • Caching of LDAP queries and responses.
  • LDAP version 3.
