SIP Trunking
Connect your existing phone numbers to OmniDimension using SIP trunking.
SIP (Session Initiation Protocol) trunking allows you to use your existing phone numbers with your OmniDimension AI agents. This guide will help you configure your telephony provider to work with our platform.
What you'll need
- A SIP-enabled phone number from a supported provider
- SIP trunking credentials from your provider
- Access to your provider's configuration panel
Supported providers
We can support any SIP provider by default — most carriers work the moment you paste credentials, and the rest take a quick manual configuration. This list grows often as we add more carriers to the fully supported column. 📡
Fully supported
These providers work by default with username / password authentication.
- Twilio
- Vonage
- RingCentral
Manual setup required
Contact support for manual configuration.
- Other SIP providers
- Custom configurations
Carrier not on the list? We'll wire it up for you.
Send us your provider's SIP credential page (a screenshot is fine) and the team will add it manually, usually within 1–2 business days.
- Email: support@omnidim.io
- Discord: join the OmniDimension community
Once it's live in the dropdown, future numbers from the same carrier import in one click for everyone.

Common issues and solutions
Import failed
Don't worry, this happens sometimes. Here's what to check:
- Double-check your SIP credentials and ensure your provider allows outbound calls
- Check your account balance / credits and verify your plan includes SIP trunking features
Calls not working
If your number imported but calls aren't connecting or dispatching:
- Verify your SIP trunk settings and ensure your plan supports outbound calls to your target regions
- Review call logs in your provider's dashboard and contact them if SIP trunking isn't enabled
Need manual setup?
For providers not in our supported list:
- Try importing with Other / Unknown first, then contact our support team if that doesn't work
- We'll manually configure your provider and get back to you once it's ready
