IP PBX System

Buy an IP PBX System in Pakistan

An IP PBX system lets your business manage extensions, incoming calls, voicemail, and call routing over its data network. On sell.biz.pk, this category lists Yeastar and Grandstream PBX models. It also includes the IP phones, network switches, and VoIP gateways that complete a setup.

This guide groups the listed models by team size, so you can build a shortlist quickly. It also explains which extra equipment you may need before you compare prices.

Choose an IP PBX System by Team Size

First, work out two numbers: how many users need an extension, and how many calls may run at the same time. However, listed capacities vary by model, so always confirm them on the product page.

Small Offices and Startups

• Yeastar S20: up to 20 users and 10 concurrent calls, with a modular design and expansion slots.
• Yeastar P520: up to 20 users and 10 concurrent calls, with Linkus UC apps built in.
• Yeastar PS20: a compact entry-level system with IVR, voicemail, and remote access.

Growing Businesses

• Yeastar S50: up to 50 users and 25 concurrent calls, with analog and GSM support.
• Yeastar P550: up to 50 users and 25 concurrent calls, with Linkus UC apps and secure remote connectivity.
• Yeastar P560: 100 users and 30 concurrent calls, expandable to 200 users and 60 calls.

Large Offices and Call Centers

• Yeastar S300: up to 300 users and 60 concurrent calls.
• Grandstream UCM6302: up to 1,000 SIP users and 150 concurrent calls.
• Grandstream UCM6304: up to 2,000 SIP users and 300 concurrent calls.
• Grandstream UCM6308A: up to 3,000 users, with built-in audio and video conferencing.

Hybrid PBX Options for Existing Phone Lines

You may not need to replace your analog phones and lines on day one. A hybrid PBX combines analog and IP calling, so you can move to VoIP in stages. For example, these models support that approach:

• Yeastar N412: hybrid analog and IP calling, with SIP and analog trunk support.
• Yeastar N824: a modular smart analog PBX that also supports SIP.
• Yeastar S412: 8 VoIP users and 8 concurrent calls, with up to 12 FXS ports.
• Grandstream UCM6510: a hybrid system with FXO and FXS ports for PSTN and SIP connections.

Equipment That Completes an IP PBX System

Although the PBX manages your calls, your staff and phone lines connect through other devices. Therefore, plan these three groups together.

IP Phones

Listings include Yealink, Fanvil, Grandstream, Cisco, Polycom, and Huawei models. Choose by role: a desk phone such as the Fanvil X4U suits general staff. Similarly, the Yealink T77U adds a 7-inch touchscreen, while the Fanvil V67 supports video calling. Finally, staff without a nearby network port can use a Wi-Fi model such as the Fanvil X301W.

Network Switches

Because voice calls need a stable network, your switch matters as well. A PoE switch can power compatible phones through the network cable, which reduces the need for separate adapters. For example, the BDCOM S2500-24P4S offers 24 PoE ports. In addition, MikroTik and Cisco switches are listed.

VoIP Gateways

A gateway connects your IP PBX system to equipment that does not use SIP. The right type depends on what you need to connect:

• FXS gateways connect analog phones and fax machines.
• FXO gateways connect analog phone lines from your provider.
• Digital gateways, such as the Yeastar TE100, connect E1, T1, or J1 lines.

What to Check Before You Buy

• Users: count your extensions today, then allow room for growth.
• Concurrent calls: estimate your busiest hour, not your average day.
• Phone lines: decide whether you will use SIP trunks, analog lines, or both.
• Compatibility: confirm that your phones and gateways work with your PBX.
• Remote work: check for mobile apps and secure remote access if staff work offsite.
• Setup and warranty: ask the seller what support and warranty the price includes.

You can also review the official product details from Yeastar and Grandstream before you decide.
