TCXC Open Voice Shield bronze

ovs.telecomsxchange.com

“Voice call fraud analysis on a SIP trunk: each call is recorded, transcribed and scored (fraud probability, category, red flags, TCPA note, block/review/allow), the route is checked for false answer supervision and the audio is graded (estimated MOS, jitter, packet loss). Operable by an agent over MCP after the person signs in through OAuth: destinations, routing, webhooks, alert rules, test calls and verdicts. A test call an agent asks for rings only after the person confirms it in the portal, opens with a recorded announcement that it is an automated test call, and presents the platform's own number or one of the account's verified numbers.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of ovs.telecomsxchange.com controls every word below.

Configure an account

After the OAuth sign-in: add destinations (the SIP host calls go on to), routing rules by prefix, IP whitelist entries, the call.analyzed webhook URL and alert rules to e-mail or to Slack channels. A destination's password or provider key, the webhook signing secret and the Slack connection are entered by the person in the portal; list_channels and list_verified_numbers read what is there.

destinationroutingwebhookalertsslackverified-numbers

Examples it gives

Add 203.0.113.20:5060 udp as the default destination and alert my Slack channel on block verdicts

Request a test call and read the verdict

place_test_call requests a call through a destination and returns status awaiting_confirm with a confirm_url; nothing rings until the person confirms on that portal page (10 minutes, or cancel_test_call). Every call opens with a recorded announcement that it is an automated, recorded test call. The caller ID is the platform's own number or a verified number; route_test (a neutral announcement) may ring any number, the known scam sample and agent calls only verified numbers. Poll get_test_call, then fetch the call, its analysis, transcript, per-leg quality and PDF report.

Examples it gives

Request a 30 second route test to my verified number through my default destination and tell me the verdict once I confirm it

Query analysed calls

List and filter calls by origin, status, analysis state, probability or SIP Call-ID; read the full analysis, route alert and transcript of any call.
