Call center infrastructure

Call centre infrastructure is the system where the operators of a Bulgarian company talk, record and report: SIP telephony, inbound and outbound calls, automated dialling with a script, recording every customer call in the CRM, and a live dashboard for the supervisor. We include the price in the quote after a demo with Your queues because it depends on the number of operators, channels and reports, while phone lines are paid to the telecom operator; we built Elite Call Center in six months, while a browser phone connected to an existing CRM can be up and running in weeks. The Contact Centre solution opens now, without registration, with calls, email, chat, Viber and Facebook in one list.

What you get

  • Telephony over a SIP line

    Inbound and outbound calls over your operator's SIP line, with a backup provider in case of an outage, as in Elite Call Center running on an A1 line.

  • Automatic dialling with a script

    The system dials the next number on the list, gives the operator a branching script and records the outcome. Inbound and outbound calls are handled by one team.

  • A recording of every call in the customer's record

    The recording is stored in the customer's CRM record, with role-based permissions and a GDPR-compliant retention period. AI assesses call quality, as in Elite Call Center.

  • Live supervisor dashboard

    Queues, callers waiting, available operators and response deadlines on one screen. Live listening, prompts and the ability to join the call.

  • All channels in one list

    Phone, email, chat, Viber, WhatsApp and Facebook with a shared history and tickets with deadlines, as in the Contact Centre solution.

  • The system is yours

    The code, recordings, customer database and reports are handed over with the project. Operators work from the office or from home through a browser.

What we build

Call centre infrastructure, to us, is everything between the phone line and the manager’s report: SIP telephony with a backup provider, a PBX with an IVR menu and queues, automated dialling for outbound teams, call recording, a CRM with a profile for every customer, tickets with response deadlines, a live dashboard, and quality and sales reports.

That is how we built Elite Call Center: Vicidial and Asterisk on an A1 SIP line with a backup provider, recording every call with encrypted storage and automatic deletion under GDPR, a custom CRM with live monitoring, whisper coaching and call barging, AI quality scoring, a supervisor dashboard, and an ERP for schedules, staff and invoicing. Saitami ERP, our own system, has the phone built into the customer profile, with recording and transcription. The Contact Centre solution shows calls, email, chat, Viber and Facebook in one list, outbound campaigns with scripts and a live dashboard; the Voice Agent shows how AI answers incoming calls and hands them over to the person on duty.

The solutions are available at demo.mmm.software and open without registration.

How the project works

First, you describe your call centre: how many operators you have, whether the calls are inbound or outbound, what scenarios you handle, and which systems you currently use. We ask about your numbers and carrier, your CRM system, your channels, and the reports your supervisor needs, then give you an indicative price. The price depends on the number of operators, channels and reports, not on minutes: those are charged by the phone carrier.

Then we run a demo using your scenarios: the operator screen, script and dashboard. The quote describes the components, integrations, exact price, timeline and anything that remains with the phone carrier, and is accepted online. Payment is made in stages, with an invoice for each stage.

We launch without interruption: the old system keeps working until the day the numbers are forwarded to the new one, which happens when everything is ready and you approve it. One team goes live first, followed by the rest. A browser phone connected to an existing CRM takes weeks; Elite Call Center, from the line to the dashboard, took six months.

What you get

A working system on your server or on a server rented for you: the PBX, operator screen, CRM, recordings, dashboard and reports. The code is kept in a repository in your name, with the access details and instructions for deploying the system elsewhere. Training for operators and supervisors, plus a document setting out the rules: who can hear which recordings, how long they are kept, and when an issue is escalated.

Operators talk through the browser, from the office or from home. After launch, we monitor the lines and recordings during the first few weeks; after that, you can continue with monthly support from us (€100-€350 per month according to our quotes) or without it.

What is not included

Phone numbers, the SIP line and minutes are arranged with a carrier and paid to the carrier. Headsets, computers and internet are yours. Fees for Viber Business, WhatsApp Business and the AI model are paid to their respective providers. The operators are not our service; we build the system your operators work in. We do not make cold calls on your behalf.

Ready-made platform or own system

Ready-made call centre platforms go live quickly and are a good choice for a small team handling standard inbound calls; you pay a carrier monthly, while the recordings and customer database sit on someone else’s server. An own system makes sense when there are many operators, when outbound campaigns are the main activity, when the CRM and phone need to be one system, and when recordings need to stay with you. The figures are on the page How Much Does Call Centre Infrastructure Cost. If a ready-made platform is enough for you, we will tell you.

When is a browser phone enough?

Not every company needs a full call centre. When the team consists of a few people and calls are to known customers, a browser phone built into the CRM is enough: click-to-call from the customer profile, with the recording and a note saved against the customer, as in Saitami ERP. This is a project measured in weeks and is at the lower end of the price range. Full infrastructure, with automatic dialling, queues, IVR, a dashboard and quality reports, makes sense for outbound campaigns, teams of dozens of operators, or a client contract that requires response deadlines and recordings. We tell you which of the two you need in the first conversation, after hearing how many calls you handle each day and what you do with them.

How we work

01

You describe your call center

How many agents, inbound or outbound calls, what scenarios, and which systems do you work with today.

02

Questions about lines and channels

We ask about the numbers, operator, CRM system, channels and reports the supervisor needs, and give you an indicative price.

03

Demo with your queues

We show the agent screen, script and dashboard with your scenarios before the proposal.

04

Written proposal

Components, connections, exact price, timeline and what remains with the phone operator.

05

Connection and go-live

We connect the lines, migrate customers and lists, train agents and supervisors, and roll out in stages without interrupting operations.

06

Monitoring and support

We monitor the lines and recordings during the first few weeks; after that, support is optional.

Frequently asked questions

Call center infrastructure: the price depends on the scope, which we set out in the proposal.

It depends on the scope, which we set out in the proposal.

Yours. The code, call recordings, customer database and reports are handed over with the project and remain on your server or on a server rented for you. There is no per-operator fee and no licence fee.

If you wish, we can maintain the project for €100-€350 per month. We specify what maintenance includes in the quote.

Yes. The numbers remain with your carrier and are forwarded to a SIP line when everything is ready and you approve it, so the old system keeps working until the last day. For Elite Call Center, we connected an A1 line to Vicidial and a CRM that stores every call recording; in Saitami ERP, the phone is built directly into the customer profile.

The development is a one-off cost included in the quote. Minutes and numbers are paid to the phone carrier at its rates, while support from us is an optional monthly line item. We do not charge per call and do not require minimum volumes.

No, we build the system; the operators are yours. For a small volume, such as a few service alerts per day, we offer a Voice Agent that answers around the clock, follows a script and forwards urgent cases to your on-duty employee.

Yes. Every call is recorded against the customer, queue, quality and sales reports are available in the dashboard, and escalation follows rules: by keyword, by status or with a single click by the operator, to an employee, team or Telegram notification.

Yes. They talk through the browser using headsets, while recordings, scripts and history remain in the system. The supervisor sees them on the dashboard in the same way.

A browser-based phone integrated with an existing CRM can be up and running in a few weeks; a full call center with autodialling, recordings and a dashboard, such as Elite Call Center, took six months. Instead of a pilot period, we create a demo with your scenarios before the proposal and roll it out in stages, starting with one team.
