Frequently Asked Questions
How quickly does CelloIP Technologies respond to project enquiries?
We respond to all project enquiries within 4 business hours during Monday–Saturday, 9AM–7PM IST. Critical or urgent enquiries sent via WhatsApp typically receive a response within 1 hour during business hours.
Does CelloIP Technologies work with international clients?
Yes. We work with clients across 30+ countries including the US, UK, Canada, Australia, Germany, UAE, and Singapore. All communication is in English via Slack and video calls scheduled to your timezone. Contracts are available in USD, GBP, EUR, and AED.
What information should I include in my project enquiry?
Include your technology preferences (Asterisk, FreeSWITCH, etc.), expected call volumes (concurrent calls, total CDRs per day), integration requirements (CRM, billing, API), deployment environment (cloud, on-premise, hybrid), and your target go-live date. The more detail you provide, the faster we can prepare an accurate proposal.
Does CelloIP Technologies offer fixed-price contracts?
Yes, for well-defined projects we offer fixed-price contracts after a paid discovery phase (typically 3–5 days). We also offer time-and-materials (T&M) billing for ongoing development and maintenance retainers. All pricing is transparent with itemised estimates before work begins.
Can I hire a dedicated CelloIP VoIP engineer?
Yes. We offer dedicated resource hiring for full-time and part-time engagements. Dedicated engineers work exclusively on your project during contracted hours and attend your team meetings. Minimum engagement is 1 month.
