Trying to push custom attributes to a live voice conversation leg using the JS SDK. The docs show PATCH /api/v2/conversations/{conversationId}/participants/{participantId} works for chat, but voice legs seem to ignore the attributes block in the request body.
const body = {
attributes: {
"cust_ref": "12345"
}
};
await api.conversationsApi.patchConversationParticipant(
convId,
legId,
body
);
Response is 204 No Content. No error. But checking the conversation details endpoint immediately after shows the attributes are still empty. Is there a different endpoint for voice, or does the SDK need a specific flag to persist these on the media server? Checking the raw network traffic shows the payload is sent correctly, so it’s not a serialization issue.
