sip-feature Support

When the UAC sends a Require: timer header is in the initial request and the Oracle® Enterprise Session Border Controller does not support session timers, and no sip-feature configuration element is configured for 'timer' for that realm, the Oracle® Enterprise Session Border Controller replies with a 420 (Bad Extension) response for 'timer'.

When the UAC sends a Require: timer header is in the initial request and the Oracle® Enterprise Session Border Controller does support session timers, the timer tag is removed from the Require: header even if a sip-feature configuration element is configured for 'timer'. This also applies for the Proxy-Require: header.

Oracle recommends you do not configure a sip feature configuration element while using the Session Timers feature.
