FAQ
My VICIdial is already installed but broken. Can you fix it?
Yes — troubleshooting existing systems is where I add the most value. Message me first and I'll diagnose before you order.
Do you work with my existing SIP provider?
Yes. Telnyx, CommPeak, Skyetel, Twilio, VoIP.ms or any custom carrier. I just need credentials
What server specs do I need?
Minimum 4 vCPU, 8GB RAM, 50GB SSD. I recommend Contabo or DigitalOcean. I can advise if unsure.
Do you provide support after delivery?
Yes — post-delivery support included for issues related to the work done. Add the Monthly Support extra for ongoing coverage.
Can you handle 100+ agent call centers?
Yes. I currently manage 150+ concurrent agents in live production. Large deployments are my specialty.
