Announcement Calls

Announcement calls are one-way voice calls. The agent dials the contact, plays the prepared welcome or announcement message, and then ends the call. Use this when you do not need the candidate or customer to answer questions.

How announcement calls work

Create an agent and choose Announcement as the agent type.
Write the message that should be played after the recipient answers.
Select the voice, language, provider credential, and Plivo calling number.
Launch from a campaign, batch, or test call.
Veytrix plays the message and hangs up after the announcement is complete.

Agent tab setup

Open Agent Setup and create or edit an agent.
Select Announcement as the agent type.
Give the agent a clear name, such as Interview Reminder Announcement.
Write the announcement in the welcome message field.
Write it as plain text for everyone. Voice agents do not substitute CSV columns, so avoid {name}-style placeholders — they would be read aloud literally.

Hello, this is a reminder from the placement team.
Your technical interview is scheduled tomorrow at 10 AM.
Please keep your phone available and join from the link shared on email.
Thank you.

Audio tab setup

Language - select the language used in the announcement text.
TTS provider - choose Cartesia, Sarvam, or ElevenLabs.
Voice - select a voice that matches the tone of the message.
Speed - keep it close to normal speed for clear phone delivery.
Credential - select the matching provider key from Settings > AI Services.

Call tab setup

Select the Plivo account or outbound number used for dialing.
Keep call timeout short because there is no conversation after the message.
Enable recording only if your policy requires proof that the message was played.
Use voicemail detection if announcements should not be counted as successful when voicemail answers.

CSV requirements

Announcement campaigns and batches use the same CSV flow as other calls. Includename and phone (email optional); the phone must be a valid Indian mobile — +91 followed by 10 digits, no spaces. Voice calls only use thename, phone and email columns; any other columns are ignored, and no variables are inserted into the spoken message.

Test before launch

Save the agent.
Place a test call to your own number.
Confirm pronunciation, speed, silence, and hangup timing.
Check Call History to confirm the call status and duration.
Launch through campaign or batch only after the message sounds correct.

If the recipient must answer questions, use Two-way Conversation instead.
