Troubleshooting
Use this page when something does not work as expected.
Start by identifying the product area: agent, phone number, knowledge, channel, billing, integration, or History.
Why it matters for your business
- Save money: fix configuration issues before they create missed calls or wrong answers.
- Work faster: narrow the issue before contacting support.
- Standardize service: use one troubleshooting path for the team.
- Delight every Guest: reduce downtime and inconsistent answers.
Agent does not sound right
Check:
- Inbound calls greeting and prompt.
- Agent settings voice and model configuration.
- Whether the latest changes were saved.
- A browser test call.
Agent cannot answer a question
Check:
- Whether the answer exists in approved knowledge.
- Whether staged content still needs review.
- Whether the prompt tells the agent to use knowledge.
- Whether the question should be escalated instead.
Phone number is not working
Check:
- The number status.
- Whether it is assigned to the right agent.
- Inbound routing.
- Outbound routing if placing calls.
- Billing/payment readiness.
- For imported numbers: provider credentials and any post-import SIP setup (especially Vonage and BYO SIP).
Cannot find numbers to buy in a country
Check:
- Whether that country has live carrier inventory right now.
- Whether Require SMS is on — turn it off if you only need voice (some markets sell voice-only local numbers).
- Number type (local vs mobile) when the UI offers a choice.
- Regulatory holds that block ordering until documents are approved.
Import Existing Number fails
Check:
- Owner role in the workspace.
- E.164 format (for example
+14155550123). - Credentials belong to the account that owns the number.
- For Telnyx: use your Telnyx API key, not Voicetta’s purchase account.
- For Twilio SMS Enabled: leave SMS off unless Twilio SMS webhooks are supported for your workspace.
SMS or WhatsApp is not replying
Check:
- Channel connection status.
- Automatic replies setting.
- Whether the phone number is connected to the channel.
- Test message behavior.
- History timeline for the Guest.
- Whether the number was bought as voice-only (Require SMS was off / no SMS capability).
Billing blocks setup
Check:
- Payment method status.
- Wallet balance.
- Auto top-up settings.
- Stripe portal or invoices.
- Owner permissions.
When to contact support
Contact support when:
- a live number cannot receive calls,
- billing or payment blocks live service,
- an integration fails after reconnecting,
- messages are delivered incorrectly,
- a knowledge upload stays stuck,
- you see repeated failures that affect Guests.
