Troubleshooting

SIP 408 request timeout
Vobiz trunk cannot reach ElevenLabs SIP servers.
  • Verify the SIP trunk address is correct (for example, abc123def.sip.vobiz.ai).
  • Check the transport type is set to TCP.
  • Verify your Vobiz trunk status is active in the Vobiz Console.
SIP authentication failed
Wrong username or password.
  • Verify username and password in Vobiz Console → Trunks.
  • Ensure credentials match exactly (case-sensitive).
  • Re-enter credentials in the ElevenLabs dashboard.
Call connects but silent
Agent configuration issue or voice not set.
  • Verify the agent has a First Message configured.
  • Check the agent has a valid voice selected.
  • Test the voice in the ElevenLabs dashboard first.
  • View call logs in the ElevenLabs Dashboard for errors.
Call doesn’t connect
Wrong phone number format or trunk configuration.
  • Use E.164 format: +919988776655 (with +).
  • Or local format: 09988776655 (without +).
  • Verify your Vobiz trunk is active.
