SIP User Parts - RFC 3261 Character Set Support

RFC 3261 specifies the range of characters allowed in a user-part, all of which are supported by the Oracle Communications Unified Session Manager. ENUM databases, however, do not support all these characters.

By default, the Oracle Communications Unified Session Manager presents SIP messages to your DNS server unchanged, assuming that your deployment uses telephone numbers only as URI user parts. You configure the Oracle Communications Unified Session Manager to support the entire range of characters allowed in user parts by enabling it on your ENUM server configuration. Upon configuration, the Oracle Communications Unified Session Manager grooms the user part appropriately for the ENUM server.
