This object 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. For example, if the first bit is set, then the telUriScheme feature is enabled. If it is zero, the feature is disabled. NO bits are set by default. /** BIT Descriptions **/ 0x80000000 : telUriScheme - Use tel Uri Scheme 'tel:' (currently unsupported). 0x40000000 : mtaFQDN - Use MTA's local FQDN instead of local IP. 0x20000000 : mwiRFC3842 - Use RFC3842 for MWI (message waiting indicator). 0x10000000 : advFlashFeatures - Enable Advanced Flash Features. 0x08000000 : rfc3323Privacyheader - Use RFC 3323 defined privacy header for caller id blocking. 0x04000000 : overrideDomain - Override the domain value in outgoing messages with the proxy setting. 0x02000000 : disableCwCid - Disable the use of caller-id during call waiting. 0x01000000 : useIpAddressOf0ForHold - Use an IP address of 0.0.0.0 and port of 0 in SDP instead of a=sendonly for hold. 0x00800000 : disable100REL - This is set if we DO NOT want to advertise that we support 100rel (must be set in MTA config file). 0x00400000 : useSrvLookups - This bit is set if we want to use SRV lookups for the server addresses (must be set in the MTA config file). 0x00200000 : rtpKeepAlive - With this bit set the endpoint will send silent packets over a held connection 0x00100000 : ignoreEarlyMedia - This bit is set if we want to ignore all media received before the remote SDP is obtained. 0x00080000 : hookflashViaInfo - With this bit set the endpoint will signal hookflash via an info message instead of locally processing it 0x00040000 : limitSdpUpdates - With this bit set, we will scan over new SDPs we generate to only increment the origin line if critical info has changed. 0x00020000 : generateRemoteRT - This bit is set if we want to generate ringback tone over the connection. 0x00010000 : playLocalRtAfterEarlyMedia - This bit is set to play local RT upon receipt of a 180 after early media is detected. 0x00008000 : removeAuthHeaders - This bit is set to remove the unneeded auth headers from a callLeg after a 401 or 407 response is received. 0x00004000 : useInactiveMedia - This bit is set to allow the MTA to hold calls using the INACTIVE media attribute. 0x00002000 : noProvisionalSdpIn1XX - This bit is set to turn off sending early media (SDP in provisional 1XX response) on incoming INVITEs with 100Rel enabled 0x00001000 : disconnectOtherCallOnEmergency - Disconnect the other call in the connection when there is an incoming or outgoing emergency call. 0x00000800 : proxyPenaltyBox - Use penalty box for unresponsive proxies 0x00000400 : playBusyToneOnReject - This bit is set to always play busy tone when an outbound call is rejected 0x00000200 : sessionTimerReInvite - Use Re-INVITE instead of UPDATE for session timer refresh 0x00000100 : emergencyOnhookSendBye - With this bit set, BYE message will be sent after an emergency call goes on-hook 0x00000080 : disableSessionTimers - Do not use SIP Session Timers (RFC 4028).This setting will only take effect after an MTA reset or full reset because it requires that the SIP stack be restarted. 0x00000040 : stutterToneHookFlash - With this bit set, stutter dial tone will be played when hook is flashed for a second call. 0x00000020 : hookflashViaInfoStd - With this bit set the endpoint will signal hookflash via an info message instead of locally processing it 0x00000010 : subscribeUAProfileXML - subscribe to UA Profile event package, application XML, including Call Forward count 0x00000008 : subscribeRegEventXML - Subscribe to reg event package, application XML 0x00000004 : preferTelUriForCid - Use TEL-URI as precedence over SIP-URI for Caller ID display 0x00000002 : callHoldWithoutReInvite. - With this bit set,the call hold will be processed locally instead of sending out reinvite 0x00000001 : restrictIncomingOffer - Use the provisioned SIP Codec Array to restrict an incoming offer
