Fetch

Prerequisites

By default requests are paginated. The default page size is 50 records though it can vary based on the system’s configuration. It is recommended to fetch CDRs by page to not overload the system on particularly busy accounts.

Clients should use the next_start_key to move to the next page on subsequent requests.

Filtering results.

KAZOO provides filters to filter out rows from the results. This can be helpful if you’re looking for rows related to each other (like the same presence_id, for instance).

Timestamps

KAZOO timestamps, unless otherwise noted, are in Gregorian seconds. Alternative timestamp formats are generally noted by the field name (e.g. unix_timestamp, rfc1036, or iso8601).

Fetch request

GET /v2/accounts/{ACCOUNT_ID}/cdrs

curl -v -X GET \
    -H "X-Auth-Token: {AUTH_TOKEN}" \
    http://{SERVER}:8000/v2/accounts/{ACCOUNT_ID}/cdrs

Fetch CDRs within a time range

curl -v -X GET \
    -H "X-Auth-Token: {AUTH_TOKEN}" \
    http://{SERVER}:8000/v2/accounts/{ACCOUNT_ID}/cdrs?created_from={FROM_TIMESTAMP}&created_to={TO_TIMESTAMP}

Convert timestamps to local timezone (vs UTC)

Get CDRs and update datetime field to local time zone (using seconds for timeoffset from UTC time) - Timestamps must still be in Gregorian time:

curl -v -X GET \
    -H "X-Auth-Token: {AUTH_TOKEN}" \
    http://{SERVER}:8000/v2/accounts/{ACCOUNT_ID}/cdrs?created_from={FROM_TIMESTAMP}&created_to={TO_TIMESTAMP}&utc_offset={SECONDS_OFFSET}

Fetch as CSV instead of JSON

curl -v -X GET \
    -H "Accept: text/csv" \
    -H "X-Auth-Token: {AUTH_TOKEN}" \
    http://{SERVER}:8000/v2/accounts/{ACCOUNT_ID}/cdrs

Fetch as CSV with defined filename

Using request headers:

curl -v -X GET \
    -H "Accept: text/csv" \
    -H "X-Auth-Token: {AUTH_TOKEN}" \
    -H "X-File-Name: {FILE_NAME}" \
    http://{SERVER}:8000/v2/accounts/{ACCOUNT_ID}/cdrs

Alternatively on the querystring:

curl -v -X GET \
    -H "Accept: text/csv" \
    -H "X-Auth-Token: {AUTH_TOKEN}" \
    http://{SERVER}:8000/v2/accounts/{ACCOUNT_ID}/cdrs?file_name={FILE_NAME}

Fetch a CDR’s details

GET /v2/accounts/{ACCOUNT_ID}/cdrs/{CDR_ID}

curl -v -X GET \
    -H "X-Auth-Token: {AUTH_TOKEN}" \
    http://{SERVER}:8000/v2/accounts/{ACCOUNT_ID}/cdrs/{CDR_ID}

Fetch interaction summary

GET /v2/accounts/{ACCOUNT_ID}/cdrs/interaction

curl -v -X GET \
    -H "X-Auth-Token: {AUTH_TOKEN}" \
    http://{SERVER}:8000/v2/accounts/{ACCOUNT_ID}/cdrs/interaction

Crossbar cdrs was extended to provide simplified interaction call detail records. It groups all CDRs that interacted with each other to form a list of calls.

GET /v2/accounts/{ACCOUNT_ID}/cdrs/legs/{INTERACTION_ID}

curl -v -X GET \
    -H "X-Auth-Token: {AUTH_TOKEN}" \
    http://{SERVER}:8000/v2/accounts/{ACCOUNT_ID}/cdrs/legs/{INTERACTION_ID}

Variations

You can select CDRs/interactions for a specific user by adding them to the URI:

GET /v2/accounts/{ACCOUNT_ID}/users/{USER_ID}/cdrs

Notes on fields

Some fields need a little more explanation to help you understand what they are telling you about the call leg.

call_direction - direction of the leg, relative to the media switch
- inbound - leg came into the media switch (typically the A-leg)
- outbound - leg started on the media switch (typically the B-leg)
hangup_cause - The reason why the call leg ended. See the FreeSWITCH Hangup Causes page for descriptions.
billing_seconds - How many seconds of the call are billable (post answer, normally)
to - Depends on the direction of the leg
- outbound - Uses the presence-id or else it uses the SIP Request address
- inbound - the SIP To header

Kazoo-specific properties

These are properties set by Kazoo for internal purposes. These are the properties found under the custom_channel_vars property at the top-level of the CDR JSON object. The non-exhaustive list of properties:

account_id - Account ID this leg belongs to
authorizing_id - Document ID used to authorize this call leg
authorizing_type - Type of document used to authorize call
- device - the call leg is to/from a known Kazoo device
- mobile - the call leg is to/from a known Kazoo mobile device
- resource - the call leg is from a known offnet carrier
- outbound_fax
bridge_id - Typically the A-leg’s call-id; helps with tracking transfers
ecallmgr_node - Which ecallmgr node is processing the call leg
fetch_id - The dialplan XML fetch ID from FreeSWITCH
realm - the SIP realm of the account
resource_id - Resource ID used for the leg; typically a carrier, local or global, that the call was routed to
username - the SIP username of the endpoint that started the leg

These properties relate to how the leg was rated and billed. Some of these properties are not accessible via Crossbar, but may exist on the CDR

reseller_billing - tag describing what billing was used for the reseller
reseller_id - Account ID of the reseller for the account of this leg
account_billing - tag describing what billing was used for the account
rate - Rate of the call
base_cost - How much the call costs to start (if per-minute)
rate_name - Name of the rate doc used
surcharge - Surcharge added to the leg
rate_minimum - Minimum number of seconds to bill for
rate_increment - Increment of seconds to bill for

Fax-specific Properties

These properties may exist on a CDR for a fax request (inbound or outbound):

fax_transfer_rate - Baud of the fax transfer
fax_bad_rows - Number of rows that failed to transfer
fax_total_pages - Number of pages in the fax (see fax_transferred_pages for how many made it)
fax_transferred_pages - Number of pages transferred
fax_ecm_used - Was ECM (error correction mode) used on the fax
fax_result_text - Error String, if any, or ‘OK’ if successful
fax_result_code - Result code of the transmission
fax_success - boolean for whether the fax was considered a success
fax_t38 - boolean for whether the fax T.38 was used

Resource Properties

All resource properties are set by the Stepswitch application.

resource_type - This property attempts to explain the reason the resource was used. The possible values are:
- offnet-origination - Inbound call from a resource/carrier to a Kazoo account
- offnet-termination - Outbound call from a Kazoo account to a resource/carrier
- onnet-origination - Inbound call from a Kazoo account to another Kazoo account
- onnet-termination - Outbound call from a Kazoo account to another Kazoo account
global_resource - This boolean is TRUE when the channel has been created by processing a resource from the offnet database, and FALSE if the resource is from an account database (local).
resource_id - This is resource document id used to create the channel
