VOIP Telephony for Business — Cheaper Calls and Full Control
VOIP telephony for business from Saitami means every company call runs over the internet instead of an old analogue line — with up to 60% lower call bills, free internal calls between offices and a full history of every conversation. We build VOIP infrastructure for Bulgarian companies from 3 to 200 employees, connect it to your CRM and ERP, and put it into real production in 2-4 weeks. Prices fixed in EUR, no lock-in to a single telecom operator, no vendor lock-in.
Why analogue telephony holds your business back
A classic phone exchange is a black box — you do not know how many calls you missed, who talked for how long, or why a customer hung up before being answered. Every new line costs telecom money, every new office needs a separate contract, and switching operator means losing numbers or paying for months of porting. VOIP telephony removes those limits and turns the phone into a measurable business tool.
- ✓Expensive calls — you pay per minute to mobile and international numbers on a decade-old tariff, with no volume discounts and no control over who talks.
- ✓Missed calls — with no queue, no routing and no statistics, customers hit a busy tone and go to a competitor while you never find out.
- ✓Zero reporting — you cannot prove how many calls each employee took, nor replay a disputed conversation with a client.
- ✓Operator lock-in — your numbers belong to the telecom, not the company, and every change goes through their approval.
- ✓Disconnected offices — a call between the warehouse and the office costs like an external call because there is no shared exchange.
What we deliver
We connect the company to a SIP trunk provider, port your existing numbers and add new local and mobile numbers in Bulgaria and the EU. See also call center infrastructure for the full solution.
We install and configure a virtual phone exchange — voice menu (IVR), queues, schedule-based routing, voicemail with email notification and recording of every call.
We link telephony to your systems — an incoming call shows the customer on screen, calls are logged to the record, and dialling is one click. See API integrations.
Staff talk from a desktop app, a mobile phone or a desk IP handset — one number follows you everywhere, including remote work.
A live dashboard with call volume, average answer time, missed calls, load by hour and by employee — the phone becomes measurable, not guesswork.
All offices and warehouses run on one exchange with short internal numbers — calls between locations are free, whether in Sofia or Plovdiv.
How we implement VOIP telephony
The process is designed so you move from the old exchange to VOIP without disrupting the business — old and new lines run in parallel until you are sure everything is stable.
1. Audit of current telephony
We review your bills for recent months, count lines and numbers, map who talks to whom and what the real load is. Output: an estimate of your savings and the capacity you need.
2. Building the infrastructure
We install the IP PBX in the cloud or on your server, configure the SIP trunk, IVR menu, queues and access rights. We test call quality and load before launch.
3. Number porting and integrations
We move the company numbers to the new provider and connect telephony to your CRM and ERP. Details in API integrations and custom software.
4. Training and go-live
We train the team on the new phones and apps, run the system in parallel with the old one and, once stable, switch off the analogue lines.
5. Support and evolution
We stay on monthly support with a fixed SLA — we monitor quality, add numbers and users, and evolve the call scenarios as you grow.
Pricing and timeline
A rollout with CRM integration and multi-office connectivity is €3,000-€8,000 depending on the number of locations. Monthly support starts at €150, with no per-user fee. Saitami is a Bulgarian team with 58 projects since 2013 and over 50 businesses served.
Frequently Asked Questions
How much does VOIP telephony for business cost?
Rollout starts from €1,500 for a small office up to 10 users — it includes a software exchange, configuration and training. A larger install with CRM integration and several offices is €3,000-€8,000. The monthly call bill is typically up to 60% lower than an analogue line because traffic runs over the internet.
Will I keep my existing numbers?
Yes. Your company landline and mobile numbers are ported to the VOIP provider via the legal portability procedure. Customers keep calling the same number without noticing the change.
Does VOIP work for remote staff?
Yes. The employee uses an app on a computer or mobile phone and receives company calls anywhere with internet. One internal number follows the person, not the desk.
What happens if the internet goes down?
We configure automatic failover — when the link is down, calls route to mobile phones or a backup line. For critical businesses we add a second internet connection as a fallback.
Can I connect telephony to my CRM?
Yes. An incoming call shows which customer is calling and their history, and conversations are logged automatically to the record. Details in API integrations.
