question

There are a few additional query parameters which will get you "closer" to where you want to be (I'll show some URL examples below). The only part that you "should" need to filter the response data for (based on the criteria you've provided) is "result" === "Missed". I've submitted a suggestion to our API Product Management team to consider adding the ability to filter on some of the Call Log Record data in the call-log requests as well. If I learn there is a way to filter by result=Missed, I will update this ticket.

Here are the query parameters you can use to filter call-logs:

• Filter by Phone Number (cannot be used with extensionNumber query param simultaneously)
  Param Name === phoneNumber
  Value Format === Number, <countryCode><areaCode><exchangeCode><identifier>
  Example === 13215551212
  
  
• Filter by Extension Number (cannot be used with phoneNumber query param simultaneously)
  Param Name === extensionNumber
  Value Format === Number, <extensionNumber> // Note, this is NOT the extension ID
  Example === 104
  
  
• Filter by Voice (Phone Call)
  Param Name === type
  Value Format === String, One of the valid Call Types, either "Voice" -or- "Fax"
  Example === Voice
  
  
• Filter by Direction
  Param Name === direction
  Value Format === String, One of the valid Call Direction strings, either "Inbound" -or- "Outbound"
  Example === Inbound

Here is a cURL example using all of these together (except extensionNumber since we cannot use that and phoneNumber together in same query):

https://platform.devtest.ringcentral.com/restapi/v1.0/account/~/call-log?type=Voice&phoneNumber=13215551212&direction=Inbound

The results of these calls will contain the appropriately time-based range (as defined by the default of last 24 hours, or by using the dateFrom and dateTo query params). Each record will have a "result" property, you will just need to filter out the results by the value "Missed" to get the records you want.

Let me know if you'd like some example code for filtering these results.
