OB_ANI [SRWS] Set to override the number recorded as the originating phone for an outbound call. This variable can be set in an IVR session in advance of making a connected outbound call on another SC-Bus channel. It can also be set in an FS file (with $var_def) to affect the ANI for a single call. A special code of X can be used to suppress the ANI, when supported, and a code of 'none' can be used to override the value set as $outbound_ani in the USR or UJP file and instead use the normal phone number as the ANI. Your telephone company may ignore the value set by this variable. PRI boards only. If you are about to transfer a call using either the Dialogic SC-Bus or the Dialogic Diva line interconnect feature, the value will be applied on the outbound call. For Commetrex BladeWare this value replaces the part of the CFSIP_CALLINGNUM value between the 'sip:' and the '@': see the comment in the $outbound_ani topic. For Dialogic Diva, the X may be followed by a number which will be inserted as the calling number but coded as restricted.  If the dialed number is marked as a toll-free number by a configuration file $phone_mask, then the OB_TF_ANI value, if defined, is used in place of the OB_ANI value.
OB_CALLSECONDS [SRW] Returns the time in seconds since the start of an outbound call, for use in postprocessing operations. Assigning any value to this variable resets it to zero.
OB_CONNSECONDS [SRW] Returns the time in seconds since the connection of an outbound call, for use in postprocessing operations. Assigning any value to this variable resets it to zero.
OB_TF_ANI[SWS] This value is used in place of the OB_ANI value if the dialed number is marked as a toll-free number by a configuration file $phone_mask.
OC_... These 'outcome' variables contain data about the transmission at the end of an outbound call. Those marked with an asterisk refer to a specific attempt number, which you can set in OC_INDEX. The OC_INDEX variable is initialized to the number of the final attempt (the same value as OC_ACOUNT).
OC_ACALLTIME [SRO] The aggregate call time in seconds for all attempts. For e-mail attempts, one decimal place of seconds is shown, and the time includes DNS/MX look-up and SMTP transmission time.

OC_INDEX [SRW] The index (from 1 to OC_ACOUNT inclusive) of the attempt to be reported by OC_... variables. Initialized to the value in OC_ACOUNT.
OC_FINAL[SRO] The value is 1 if no further attempts were scheduled after this attempt, 0 otherwise.
OC_MANUAL* [SRO] Returns an empty value if the transaction has not been manually resubmitted. Returns 'YES' if the transaction has been manually resubmitted (indicating more than one success and/or final failure in the attempt history). Returns 'THIS' if the attempt is the first after a manual resubmission.

OC_TIME* [SRO] The clock-time at the start of the attempt (HH:MM:SS).
OMA_WARNING[CV >M] Can be set to a value of none to suppress warnings that no COPIAFACTS engine is running.  Currently this variable is only used by FFMRGMV.
ONECALL_... [SRO] These 'onecall' variables contain data about the fax sent in a one-call fax on demand transmission. They can only be used in an infobox reached after trapping states END_FAX or ABORT_FAX.
ONECALL_FAXCSID [SRO] The CSID (answerback) of the remote fax machine.

OPSYS [SRO] Contains a string representing the operating system major and minor version, for example 6.1 for Windows 7.
OTF_These variables are used to supply or record specific parameters for the BladeWare SIP implementation.  See also BLADEWARE_RECEIVE_TIMEOUT_MINUTES and OTF_ environment variables.
OTF_OBDIRECT_ACCEPT_MEDIA[CV >C] Used to set up the media preferences for BladeWare SIP direct outbound calls (those where the called number starts sip:).  If not supplied, the OTF_OUTBOUND_ACCEPT_MEDIA value is used. See also Media Preferences.
OTF_OBDIRECT_OFFER_MEDIA[CV >C] Used to set up the media preferences for BladeWare SIP direct outbound calls (those where the called number starts sip:).  If not supplied, the OTF_OUTBOUND_OFFER_MEDIA value is used. See also Media Preferences.
OTF_DISABLE_ECM[CV >C] If non-empty, disables ECM for BladeWare outbound calls.
OTF_DISABLE_V34[CV >C] If non-empty, disables V.34 for BladeWare outbound calls.
OTF_MODE[CV C>] Set after a fax transmission to either 'G.711' or 'T.38' depending on the transmission mode.
OTF_INBOUND_ACCEPT_MEDIA[CV >C] Used to set up the media preferences for BladeWare SIP inbound calls. The value of this parameter is selected in OTFCONFIG.  See also Media Preferences.
OTF_RECEIVE_DISABLE_V17[CV >C] If non-empty, disables V.17 for inbound calls.  To restrict inbound calls to 9600 baud, use this variable and OTF_RECEIVE_DISABLE_V34.  However Commetrex advise that this may not provide the expected improvement in FoIP results that would result from applying a similar limit on a 'bad' TDM or analog line.
OTF_RECEIVE_DISABLE_V34[CV >C] If non-empty, disables V.34 for BladeWare inbound calls.
OTF_RECEIVE_DISABLE_ECM[CV >C] If non-empty, disables ECM for BladeWare inbound calls.
OTF_INBOUND_OFFER_MEDIA[CV >C] Used to set up the media preferences for BladeWare SIP inbound calls. The value of this parameter is selected in OTFCONFIG. See also Media Preferences.
OTF_RED_DATAFRAMECOUNT[CV >C] Overrides the redundancy data frame count
OTF_RED_SIGNALFRAMECOUNT[CV >C] Overrides the signal data frame count
OTF_REINVITE_DELAY, OTF_REINVITE_DURATION[CV C>]  These variables are set on an outbound call to the number of milliseconds that elapse before a T.38 re-invite occurs and the number of milliseconds after this for T.38 to become active.  The values can be saved in DATA6 and DATA7 of the DBF log file using a $log_options keyword of REINVITE.
OTF_OUTBOUND_ACCEPT_MEDIA[CV >C] Used to set up the media preferences for BladeWare SIP outbound calls.  The value of this parameter is selected in OTFCONFIG. See also Media Preferences.
OTF_OUTBOUND_OFFER_MEDIA[CV >C] Used to set up the media preferences for BladeWare SIP outbound calls. The value of this parameter is selected in OTFCONFIG. See also Media Preferences.
OTF_USE_PLUS[CV >C] a non-empty value in this variable causes a number starting with the characters defined as $country_prefix to have those characters replaced by a + character immediately before the call is placed.
OTF_USE_SIPTO[CV >C] a non-empty value in this variable causes the SIP To: URI to be used to provide the DNIS number if present.  This is required for incoming calls from the Babytel service provider, and perhaps others.
OUTCOME_VALUE[SRO] Contains the internal code which directs processing of an outbound call outcome: 0 for a successful transmission, -1 for final failure, or a positive number of seconds representing the scheduled delay to the next attempt. This value may be accessed for special purposes in an infoboxall postprocess or after trapping a suitable state.  If accessed before the outcome has been determined, the value returned will be @EMPTY.
OUTCOME_nnnn[CV >C] Used to supply an override to the outcome (SMR) parameters for the call.  The nnnn represents the four-digit non-zero outcome code to be overridden, with leading zeros if necessary.  The value is the the set of override elements corresponding to columns 3 to 6 of the SMR entry, comma-separated.  All four elements are required, and the whole value should be enclosed in double-quotes, not the outcome description.  Use this feature carefully and do not change existing 'Z' outcomes, which may have not have useful consequences. Important: this override specifies how the outcome is recorded, not the outcome itself.  For example you could theoretically treat a 'missing attachment' outcome as a success by specifying:
  $var_def OUTCOME_0150 "S,0,0,Missing attachment"
but the e-mail would still have failed, in the absence of an e-mail option to ignore missing attachments when the e-mail is being sent.
OWNER[SRO] Contains the owner mailbox owner name from $owner_name.
