When calling in, the AI starts giving it’s initial greeting before quickly cutting out completely. If the caller says anything after that, the AI will proceed like normal, but the audio dropping right at the beginning of the call is causing a lot of callers to hang up prematurely.
Hi @dan.teisberg Here’s what we found on call_6d9c01866c8c8137ddd8583c116 and a few sibling calls today:
It’s not a barge-in or interruption issue — there was no interrupt event on the agent runtime, no early caller speech, and your interruption sensitivity is low.
It’s also not a SIP / carrier issue — the signaling and media setup were clean on those calls.
What we observed is that the TTS audio stream powering the greeting closed mid-utterance after only the first few words on the affected calls, while a sibling call on the same agent rendered the full greeting normally. We’re seeing the same TTS streaming instability across other workspaces today, so this isn’t specific to your agent, voice, or pronunciation dictionary.
Nothing on your agent config is the cause — interruptionSensitivity (0.3), denoisingMode, the pronunciation dictionary, and begin_message_delay_ms are all fine as-is.
Interim options that can reduce caller drop-offs while the upstream stability is being looked into:
Shorten the begin message to one short sentence (a shorter first utterance is less exposed to a mid-stream close).
On a test agent, try a different voice and confirm whether the symptom reduces — useful as a data point, not a required change.
