Monitor Recordings

Aculab cloud has a facility to record all the incoming audio received from outbound calls placed by your applications, starting from any early media received before the call is answered.

This is useful for debugging problems with calling specific phone numbers - for example Live Speaker Detection misclassification, or hearing the announcement explaining why calls to a number are being rejected, perhaps because the number has changed.

This document describes the web services that can be used to discover the files which have been recorded by the monitor for a given application instance, and then download them.

Please note that as this is a debug facility, it is not enabled by default on Aculab Cloud accounts. Please This email address is being protected from spambots. You need JavaScript enabled to view it. if you would like it to be enabled for you.

 This is a low level API. For information on higher level APIs see the Web Services Language Wrappers
