1.

Call Start Time

The call start time in the format YYYY/MM/DD HH:MM:SS. This is based on the system time including any DST offset.

• All records relating to the same call, that is having the same Call ID, have the same Call Start Time.

• If the system has Call Splitting for Diverts enabled, the Call Start Time is changed to the time the forward occurred for all records following that stage of the call. However, the records for the externally forwarded call retain the original Call ID.

2.

Connected Time

Duration of the connected part of the call in HH:MM:SS format. This does not include ringing, held and parked time. A lost or failed call will have a duration of 00:00:00. The total duration of a record is calculated as Connected Time + Ring Time + Hold Time + Park Time.

3.

Ring Time

Duration of the ring part of the call in seconds.

• For inbound calls, this represents the interval between the call arriving at the switch and it being answered. It does not match the time a call rang at an individual extension.

• For outbound calls, this indicates the interval between the call being initiated and being answered at the remote end if supported by the trunk type. Analog trunks are not able to detect remote answer and therefore cannot provide a ring duration for outbound calls.

4.

Caller

The caller’s number. If the call originated at an extension, this is the extension number. If the call originated externally, this is the CLI of the caller if available, otherwise blank. For SIP trunks, the field can contain the number plus IP address. For example, 12345@192.0.2.123.

5.

Direction

The direction of the call ; I for inbound, O for outbound. This value can be used in conjunction with the Is Internal value below to determine the call type.

6.

Called Number

This is the number called by the system. For a call that is transferred, this field shows the original called number, not the number of the party who transferred the call.

• Internal calls – The extension, group or short code called

• Inbound calls – The target extension number for the call

• Outbound calls – The dialed digits

• Voice Mail – Calls to a user's own voicemail mailbox

7.

Dialed Number

For internal calls and outbound calls, this is identical to the Called Number above. For inbound calls, this is the DDI of the incoming caller.

8.

Account Code

The last account code attached to the call.

9.

Is Internal

This field indicates whether both parties on the call are internal (1) or not (0). Note that calls to destinations on other switches in a network are treated as internal. This value can be used in conjunction with the Direction value above to determine the call type as follows:

10.

Call ID

This is a numerical identifier, which is incremented for each unique call. If the call has generates several SMDR records, each record has the same Call ID. Note that the Call ID is restarted from 1,000,000 following any system restart.

11.

Continuation

This value indicates if the call has any further records with the same Call ID. It is 1 if there is a further record, otherwise 0.

12.

Party1 Device

The device 1 number. This is usually the call initiator though in some scenarios, such as conferences, this may vary. If an extension/hunt group is involved in the call, its details have priority over any trunk. That includes remote network destinations.

13.

Party1 Name

The name of the device. For an extension or agent, this is the user name encoded in UTF-8.

14.

Party2 Device

The other party for the call segment. Encoded as per Party1 Device above. For barred calls, this field shows Barred.

15.

Party2 Name

The other parties name. See Party1 Name above. For barred calls, this field shows Barred.

16.

Hold Time

The number of seconds the call has been held during this call segment.

17.

Park Time

The number of seconds the call has been parked during this call segment.

18.

Authorization Valid

This field is used for authorization codes. This field shows 1 for valid authorization or 0 for invalid authorization. This is Blank, no code is used.

19.

Authorization Code

For security, this field shows n/a regardless of the authorization code used. This is blank, no code is used.

20.

User Charged

This and fields 21 to 27 are used for ISDN Advice of Charge (AoC). If blank, AoC is not being used. This field indicates the user to which the call charge has been assigned. This is not necessarily the user involved in the call.

21.

Call Charge

The total call charge calculated using the line cost per unit and user markup.

22.

Currency

The currency. This is a system wide setting set in the system configuration.

23.

Amount at Last User Change

The current AoC amount at user change.

24.

Call Units

The total call units.

25.

Units at Last User Change

The current AoC units at user change.

26.

Cost per Unit

This value is set in the system configuration against each line on which AoC signalling is set. The values are 1/10,000th of a currency unit. For example, if the call cost per unit is £1.07, a value of 10700 should be set on the line.

27.

Mark Up

Indicates the mark up value set in the system configuration for the user to which the call is being charged. The field is in units of 1/100th, for example an entry of 100 is a markup factor of 1 .

28.

External Targeting Cause

This field indicates who or what caused the external call and a reason code. For example U FU indicates that the external call was caused by the Forward Unconditional settings of a User.

29.

External Targeter ID

The associated name of the targeter indicated in the External Targeting Cause field.

• For hunt groups and users, this is their name in the system configuration.

• For an incoming call route, this is the route’s Tag value if set, otherwise ICR.

30.

External Targeted Number

This field is used for forwarded, Incoming Call Route targeted and mobile twin calls to an external line. It shows the external number called by the system as a result of the off-switch targeting whereas other called fields give the original number dialled.

31.

Calling Party Server IP Address

This IP address identifies the server where the calling extension is logged in.

32.

Unique Call ID for the Caller Extension

Numerical value that is a unique identifier of the call on the server where the call was initiated.

33.

Called Party Server IP Address

This IP address identifies the server where the called extension is logged in. If the field does not contain an IP address, then the call is to a trunk outside the IP Office network.

34.

Unique Call ID for the Called Extension

Numerical value that is a unique identifier of the call on the server where the called extension is logged in.

35.

SMDR Record Time

The system date and time, not including any DST offset, at which the SMDR record was generated. It uses the format YYYY/MM/DD HH:MM:SS.

36.

Caller Consent Directive

This field is used for calls going through an auto-attendant service that is configured to ask for caller consent to some choice.

• 0 = Consent Not Requested

• 2 = Consent Given

• 6 = Consent Denied

37.

Calling Number Verification

Show the authentication level provided by the ISP on SIP lines configured to use calling number verification. Shows A, B, C or N/A is not authentication level information provided. A record is still shown for calls which the system rejects due to failed authentication. For more details, see SIP Calling Number Verification (STIR/SHAKEN).
