Tel URI (RFC 3966) is a unique identifier that is expressed using either an Address-of-Record or a Dial String. Feature F-1291 adds tel URI support to the IMG 2020. With the inclusion of this feature, the IMG 2020 can receive the tel URI information in a SIP request of an incoming call and pass the same tel URI information to the outgoing SIP leg. The tel URI will be separated into two parts: the phone number and the optional parameters. This will allow the phone number to be used for routing in the same way as for SIP URI while the optional parameters can still be sent out as received. The tel URI functionality is by default enabled and cannot be disabled. Refer to the information below.
