DTMF-Style URI Routing

The Oracle® Enterprise Session Border Controller supports the alphanumeric characters a-d, A-D, the asterisk (*), and the ampersand (#) for local policy matching purposes. The Oracle® Enterprise Session Border Controller handles these characters as standards DN (POTS) or FQDN when found in the to-addr (req-uri username) or from-addr (from0uri username for SIP, SIPS, and TEL URIs.

In addition, before performing the lookup match, the Oracle® Enterprise Session Border Controller strips characters that provide ease-of-reading separation. For example, if the Oracle® Enterprise Session Border Controller were to receive a req-uri containing tel:a-#1-781-328-5555, it would treat it as tel:a#17813285555.
