Anyone knows the technical requirements for such a huge project? I'm signing one of the best call center companies in Europe

@beboney That's fantastic to hear! For a project of this scale, especially when dealing with voice APIs and call centers, there are several technical requirements you'll need to consider: 1. **Infrastructure**: Ensure you have robust server infrastructure that can handle high call volumes with minimal latency. This may involve cloud services with auto-scaling capabilities. 2. **Telephony Integration**: Since you're using Twilio for receiving inbound phone calls, you'll need to integrate Twilio's APIs with your systems. Make sure you have the necessary credentials and understand Twilio's API for call handling. 3. **Custom Model**: If you're using a custom model for voice recognition or other purposes, ensure that it's well-trained and tested for the languages and accents it will encounter in the call center. 4. **Cost Management**: Keep track of the costs associated with Deepgram, your custom model, and PlayHT. You'll need to multiply these by your expected call volume to budget accurately. 5. **Compliance and Security**: Adhere to data protection regulations such as GDPR in Europe, and ensure that your system is secure against potential breaches. 6. **Quality Assurance**: Implement monitoring and logging to track the performance of your voice pipeline and quickly address any issues. 7. **Scalability**: Plan for future growth, ensuring that your system can scale up as call volumes increase. 8. **Disaster Recovery**: Have a plan in place for system outages or other issues to minimize downtime. 9. **Support and Maintenance**: Ensure you have a technical support team ready to handle any issues that arise. 10. **Documentation and Training**: Provide thorough documentation and training for the call center staff on how to use the system. If you need more detailed information or assistance with specific aspects of your project, please don't hesitate to ask!

No twilio and no vonage

You can read this guide; it showcases how you can connect with your SIP provider. https://www.notion.so/SIP-be5179f856e046688c69eba817e7fcc3 https://www.notion.so/SIP-Inbound-Guide-1f0789ae62024748a62a6d81076b9f32 https://www.notion.so/SIP-Outbound-Guide-997d66df35284295b7149fc10c82f3e8 And do let me know if you need any other help.

I am connecting to this thread. As I see in the provided documentation always Twilio number is needed for inbound calls. But basically I don't want to call Twilio number. Let me explain why: my client is from Bahrain, so if the inbound call is coming to him we can redirect it to another number with VAPI assistant but this number should be Babraini number to avoid international calls charge. However Twilio doesn't provide Bahraini numbers and doesn't suport parking Bahraini SIP. I have a Bahraini SIP number - is it possible to connect it to VAPI directly?

You need a SIP provider basically local telephony which has given you Bahraini number and then you can connect it with Vapi. Twilio is here a barely an example to showcase how to use SIP with Vapi.

OK, created. Telnyx has the same limitations as Twilio. I checked it already
