IP PBX Systems

An IP PBX is a telephone system that manages internal calls and external lines over the computer network. We set up the IP PBX around the way you work, connect it to your existing lines and phones, and bring your employees outside the office into the same system.

WHAT IT DELIVERS

What it adds to your building

  • 01

    Your extension is not tied to a desk.

    Employees make and receive calls on the same extension number: on an IP phone in the office, on a computer at home, or with an app on their mobile phone in the field.

  • 02

    Branches work as one phone system.

    Calls between locations run over the network as internal calls. Whichever branch a customer calls, the call is routed to the right person.

  • 03

    No missed calls.

    We set up the auto attendant, call groups, voicemail and after-hours routing rules to match your workflow.

  • 04

    You see what is happening.

    Who called whom, how many calls went unanswered, how much each line was used? Reports and, where needed, call recordings come straight from the IP PBX.

SCOPE

What is included?

Components we install in an IP PBX project:

  • IP PBX: hardware appliance, installed on a server or running on a virtual machine
  • Gateways for SIP trunk, analog and digital line connections
  • Desk IP phones, DECT cordless phones and conference devices
  • FXS adapters for existing analog phones
  • Auto attendant (IVR), voicemail and call groups
  • Call recording, call accounting and call reporting
  • Remote work with mobile and desktop apps
  • A dedicated VLAN for voice traffic, QoS settings and PoE switches
  • Call center queues and agent screens

PROCESS

How we build it

  1. Site survey and call flow

    We inspect the existing phone system, line types, number of extensions and cabling on site. We map with you the path a call follows from the moment it reaches your company until it is answered.

  2. Network preparation

    We configure the VLAN and priority (QoS) settings for voice traffic and check PoE capacity for the phones. Most voice quality problems come from the network, not the IP PBX.

  3. Installation and numbering plan

    The IP PBX, line connections, phones, extension numbering plan and routing rules are set up.

  4. Cutover and testing

    We move from the old system to the new one on a weekend or outside working hours. We test outbound calls, inbound calls, routing and emergency call scenarios one by one.

  5. Training and maintenance

    We train users and the system administrator and tie software updates to the maintenance plan.

TECHNICAL NOTES

What we look at in the design

Voice quality starts in the network

Voice is far more sensitive to delay and packet loss than data. We keep voice traffic in a separate VLAN and mark it as priority (QoS) on the switches. For remote branches and remote workers, we choose the codec based on connection quality.

IP PBX security

An IP PBX exposed to the internet with weak passwords can lead to high bills from unauthorized international calls. We do not expose the management interface, keep extension passwords strong, put international calling behind permissions and define rules that block suspicious traffic.

Call recording and KVKK

Call recordings are personal data. Informing callers about recording, who can access recordings and how long they are kept should be set by your organization’s policy under KVKK (Turkish Personal Data Protection Law No. 6698). We set up the IP PBX so you can apply these decisions: an information announcement, authorization and deletion by retention period. (Legal assessment is the responsibility of your organization’s legal counsel.)

FAQ

Frequently asked questions

What is an IP PBX?

An IP PBX is a phone system that manages calls over the computer network. It brings internal calls, external lines, routing, voicemail and reporting into one system. Phones connect to a network cable or Wi-Fi instead of a separate telephone cable.

What is the difference between an IP PBX and an analog PBX?

An analog PBX uses a separate line and cable for each phone; an IP PBX runs over your existing computer network. With an IP PBX it is much easier to add extensions, connect branches and bring remote workers into the system.

How much does an IP PBX cost?

The cost depends mostly on the number of extensions, the number and type of lines, the features you need (call recording, call center, reporting) and the phone models. Whether existing phones and cabling can be reused also affects the total. We prepare an itemized quote after the site survey.

Can existing analog phones be used with an IP PBX?

Yes. Analog phones can be connected to an IP PBX through FXS adapters or gateways. This lets you make the transition in phases, according to your budget, and replace phones over time.

How do remote workers connect to an IP PBX?

They use their office extension numbers with an app (softphone) installed on a computer or mobile phone. We set up the connection over an encrypted, authorized structure, not by exposing the IP PBX to the internet. From our base in Ankara, we connect branches and sites across Türkiye to the same IP PBX.

What is a SIP trunk?

A SIP trunk means getting phone lines from the carrier over an internet or data connection instead of a physical cable. Many simultaneous calls can run over the same connection, and the number of lines can be increased as needed.
