- To improve the visibility into why outbound call dialing fails, we are refactoring the disconnection reasons and call status field for these unconnected cals.
- existing disconnections reasons related to unconnected calls:
dial_failed
, dial_busy
, dial_no_answer
will stay, but dial_failed
will contain less scenarios — representing cases where sip error codes are not available, or error unknown.
- new disconnection reasons:
invalid_destination
: representing cases where destination phone number is invalid.
telephony_provider_permission_denied
: representing cases where the sip trunk authentication failed.
telephony_provider_unavailable
: representing cases where the telephony provider is not available or have errors.
sip_routing_error
: representing cases where there are loops or issues with the sip routing.
marked_as_spam
: representing cases where the call is marked as spam.
user_declined
: representing cases where the user explicitly declined the call.
- these unconnected calls will not have a status of
error
, but instead will have a status of not_connected
. This changes will be a breaking change for some user’s existing codebase, so it’s recommended to not rely on status filter to find these unconnected calls.
warm_transfer_option
and show_transferee_as_caller
of TransferCallTool
will be replaced by public_handoff_option
and show_transferee_as_caller
under a new data structure transfer_option
of TransferCallTool
, respectively.
- voicemail detection related settings in agent are migrating to a new data structure
voicemail_option
.
- original settings:
enable_voicemail_detection
, voicemail_message
is still supported in API until 6/30/2025, after that it will be deprecated.
voicemail_detection_timeout_ms
setting has been removed, as it’s not longer needed by the system.
enable_transcription_formatting
setting in agent is deprecated. Setting that is a no-op now.
