This object is like sipCfgSipFeatureSwitch. It is used to enable features of the Arris SIP MTA. From left to right, the specified bit indicates whether or not the corresponding feature is enabled/disabled. For example, if the first bit is set, then the PublishTimestampsDST feature is enabled. If it is zero, the feature is disabled. NO bits are set by default. /** BIT Descriptions **/ 0x80000000 : publishTimestampsDST - With this bit set, the Timestamps in PUBLISH will be transfered to DST. 0x40000000 : playRtpForSecond183WithoutSdp - With this bit set, the RTP can continue to play on receiving second 183 without SDP. 0x20000000 : addSipInstanceToContact - With this bit set, add the sipInstance(based on RFC 5626) to Contact header in REGISTER and INVITE. 0x10000000 : notPopulateFirstPAURIFrom200OK - With this bit set, don't populate IMPUID with the first P-Associated-URI header from 200 OK to REGISTER. 0x08000000 : judgeSDPWhileReturnFalse - With this bit set, judge SDP with o= while SDPChange return FALSE. 0x04000000 : tcpFailTryUDP - With this bit set,when a TCP sip message fails,sip message should be send in UDP. 0x02000000 : reuseTCPConnection - With this bit set, SIP MTA will reuse TCP connection. 0x01000000 : sdpEndsWithEmptyLine0x0d0a - With this bit set, add an empty line to the end of SDP of INVITE. 0x00800000 : doNotRedirect3xxResponseForInvite - With this bit set, 3xx response to an INVITE will not be redirected.
