## General Steps for Implementation:
1. Acquire a Local Number: Get a phone number from a provider that supports SIP trunking
2. Configure SIP Trunk: Set up your SIP trunk with the provider
3. Set Up PBX or VoIP System: This manages your phone calls
4. Integrate with VAPI: Connect your SIP trunk to VAPI
5. Test Your Setup: Make test calls to ensure everything works
## Simplified Approach:
You can use any SIP softphone (like [Zoiper](https://www.zoiper.com/) or [Linphone](https://www.linphone.org/)) to test the Assistant by simply dialing sip:username@sip.vapi.ai
- no authentication or SIP registration required!
For a more detailed step-by-step guide, check out the [Telnyx SIP Integration Guide](https://docs.vapi.ai/advanced/sip/telnyx) which provides visual instructions for setting up SIP integration through their interface.
There's also a helpful video tutorial on connecting 3CX with Vapi via Twilio at [this YouTube link]().
Is there a specific part of the SIP integration process you're finding most challenging that I can help clarify further?Vapi Support Bot
