Appendix: SMDR

For IP Office 4.2+, the IP Office control unit is able to send SMDR (Station Message Detail Reporting) records to a specified IP address and port.

Typically an SMDR record is output for each call between two parties (internal and or external) that is handled by the IP Office system. In some scenarios, for examples transfers, where a call involves multiple parties then multiple SMDR records may be output for each part of the call. See SMDR Examples.

Each SMDR record contains call information in a comma-separated format (CSV) format, that is variable-width fields with each field separated by commas. See SMDR Fields.

Unless otherwise stated, the SMDR referred to in this documentation is the SMDR output direct from the IP Office rather than that output via the IP Office Delta Server application. Delta Server SMDR output is still supported but not if using direct SMDR output from the IP Office. See Delta Server SMDR Differences below.

 

Enabling IP Office SMDR

1.Receive the configuration from the IP Office system.
2.Select System and then select the CDR/SMDR tab.
3.Use the Output drop down box to select SMDR only.
4.In the SMDR settings, enter the required IP Address and TCP Port.

 

SMDR Records

An SMDR record is generated for each call between two devices on the IP Office system. Devices include extensions, trunk lines (or channels on a trunk), voicemail channels, conference channels and IP Office tones.

Calls which are not presented to another device do not generate an SMDR record. For example internal users dialing short code that simply changes a configuration setting.

The SMDR record is generated when the call ends, therefore the order of the SMDR records output does not match the call start times.

Each record contains a call ID which is increased by 1 for each subsequent call.

When a call moves from one device to another, an SMDR record is output for the first part of the call and an additional SMDR record will be generated for the subsequent part of the call.

Each of these records will have the same Call ID.

Each record for a call indicates in the Continuation field if there will be further records for the same call.

 

Call Times

Each SMDR record can include values for ringing time, connected time, held time and parked time. The total duration of an SMDR record is the sum of those values.

The time when a call is not in any one of the states above, for example when one party to the call has disconnected, is not measured and included in SMDR records.

Where announcements are being used, the connected time for a call begins either when the call is answered or the first announcement begins.

All times are rounded up to the nearest second.

Each SMDR record has a Call Start time taken from the system clock time. For calls being transferred or subject to call splitting, each of the multiple SMDR records will have the same Call Start time as the original call.

 

Delta Server SMDR Differences

Previously SMDR records were obtained using the IP Office Delta Server application running on a PC connected to the IP Office system via the LAN. This method was used for pre-IP Office 4.2 systems. Delta Server SMDR output is still supported with IP Office 4.2+ systems. However it is not supported if also outputting direct SMDR records from the IP Office.

There are a number of differences between the IP Office SMDR output and that output by the IP Office Delta Server application. The key differences are:

•Advice of Charge and Authorization Code Fields are Included as Standard
These fields are optional in the Delta Server SMDR output. They are included as standard in the IP Office SMDR output.
•Additional Fields are Included for External Outgoing Call Routing
The IP Office SMDR output can include additional external targeting fields for calls routed out via external lines. These fields indicate what device targeted the call externally, how, and to what number.
•Call ID Starting Number
The Call ID is always reset whenever the IP Office system is restarted and then incremented by 1 for each subsequent call that is not a continuation of a previous call.
•The Call ID used by the Delta Server applications starts from 1.
•The Call ID used for IP Office SMDR starts from 1,000,000.
•Small Community Network
The following differences apply for calls to and from SCN destinations.
•IP Office SMDR indicates calls across an SCN as internal.
•IP Office SMDR inserts the hunt group or user name of the remote SCN party rather than the local line used.
•Parked and Held Time
For parked calls, the Delta Server included the time a call was parked in both the Park Time and Hold Time fields. The IP Office SMDR uses just the Park Time field.
•Additional Records Through Call Splitting
The IP Office supports Call Splitting for Diverts which produces separate initial call and forwarded call records. This applies for calls forwarded by forward unconditional, forward on no answer, forward on busy, DND or mobile twinning. It also applies to calls forwarded off-switch by an incoming call route. The two sets of records will have the same Call ID. The call time fields of the forward call record are reset from the moment of forwarding on the external trunk.
