Question 1

What is VoIP and how does it work?

Accepted Answer

VoIP (Voice over Internet Protocol) transmits phone calls over your internet connection instead of traditional telephone lines. Business VoIP systems replace physical PBX hardware with software-based phone systems that offer richer features (call queuing, IVR, voicemail to email, call recording, mobile apps) at lower cost. Calls are made through IP phones (physical desk phones) or softphone apps on computers and smartphones.

Question 2

Is VoIP allowed in the UAE?

Accepted Answer

Licensed business VoIP services are permitted in the UAE. Consumer-grade VoIP apps (WhatsApp Voice, Skype consumer, FaceTime) have historically faced restrictions. For business use, VoIP systems operating through licensed SIP trunk providers (such as Etisalat or Du business SIP services, or international providers with UAE DID numbers) are fully compliant. We help businesses deploy VoIP in a UAE-compliant manner.

Question 3

What VoIP systems does Dubai IT AMC support?

Accepted Answer

We install and support 3CX (one of the most popular business phone systems globally and UAE-compliant), Cisco Unified Communications Manager (CUCM) and Cisco Webex Calling, Microsoft Teams Direct Routing, Yealink IP phones, Polycom/Poly endpoints, and Grandstream. For most UAE SMEs, 3CX on-premises or cloud is our recommended solution.

Question 4

What is a SIP trunk and do I need one?

Accepted Answer

A SIP trunk is the connection between your VoIP system and the public telephone network — it is the 'line' that allows your VoIP system to make and receive external calls. You need a SIP trunk from a licensed provider. In the UAE, we work with Etisalat (e&) Business SIP, Du Business SIP, and international providers offering UAE DID numbers.

Question 5

What is 3CX and why is it popular in the UAE?

Accepted Answer

3CX is a software-based PBX that runs on Windows or Linux (on-premises or cloud). It is popular in the UAE because it is cost-effective (no per-seat licensing for the phone system itself), feature-rich (IVR, call recording, live chat, video conferencing, CRM integration), and has strong partner support in the region. We install and support 3CX for businesses of all sizes.

Question 6

How do I ensure good VoIP call quality?

Accepted Answer

VoIP call quality depends on: sufficient internet bandwidth (allow 100kbps per concurrent call, minimum 10Mbps upload), low latency (under 150ms to SIP provider), Quality of Service (QoS) configuration on your router and switches to prioritise voice traffic, and a stable ISP connection. Poor quality is almost always a network configuration issue — we diagnose and resolve call quality problems.

Question 7

Can my team use mobile phones with our office VoIP system?

Accepted Answer

Yes. Most business VoIP systems (including 3CX, Microsoft Teams, and Cisco Webex) offer mobile apps that extend your office phone system to smartphones. Staff can make and receive calls using their business number from their mobile — ideal for remote workers and staff who travel within the UAE.

Question 8

What is an IVR (Interactive Voice Response) and how do I set one up?

Accepted Answer

An IVR is an automated phone menu (e.g., 'Press 1 for Sales, Press 2 for Support'). We design, record, and configure IVR menus in your VoIP system. A well-designed IVR routes callers efficiently, reduces hold times, and gives your business a professional appearance. We support both Arabic and English IVR prompts.

Question 9

Can I keep my existing phone numbers when switching to VoIP?

Accepted Answer

Yes — this is called number porting. Your existing UAE landline numbers (e.g., 04-XXX XXXX) can typically be ported to a SIP trunk provider, preserving business continuity. The porting process typically takes 5–15 business days. We manage the porting process and coordinate with your outgoing telecoms provider.

Question 10

How do I record calls in my business and store recordings compliantly?

Accepted Answer

Call recording is a standard feature in most business VoIP systems. Recordings are stored on your server or in the cloud. UAE regulations require call parties to be informed that calls may be recorded. We configure compliant recording policies, set up automated announcement messages, and advise on retention periods appropriate to your industry.
