VoIP Gateways

Buy a VoIP Gateway in Pakistan

A VoIP gateway connects analog phones, analog lines, or digital E1 circuits to a modern SIP phone system. As a result, you can move to VoIP without replacing all of your existing equipment. On sell.biz.pk, this category lists Grandstream, Yeastar, Dinstar, Cisco, and OpenVox models for use with an IP PBX system.

This guide groups the listed models by the equipment they connect, so you can build a shortlist quickly. It also explains how to choose the right port type and count before you compare prices.

Choose a VoIP Gateway by Connection Type

First, identify what you need to connect. FXS, FXO, and digital models solve different problems, so the port type matters more than the brand. However, listed features vary by model, so always confirm them on the product page.

FXS Models for Analog Phones and Fax

An FXS VoIP gateway connects devices such as analog phones and fax machines. Choose a model by the number of devices you need to keep.

• Dinstar DAG1000-4S: 4 FXS ports in a compact desktop design, with T.38 fax support.
• Yeastar TA800: 8 FXS ports, with SIP and IAX2 support.
• Cisco SPA8000-G5: 8 FXS ports, with T.38 fax support and remote provisioning.
• Yeastar TA1600: 16 FXS ports, with SIP and IAX2 support.
• Grandstream GXW4224 V2: 24 FXS ports in a rack-mountable design.
• Grandstream GXW4232: 32 FXS ports for larger sites, such as hotels and hospitals.
• Grandstream GXW4248 V2: 48 FXS ports, with TLS and SRTP encryption.
• Dinstar DAG2500-96S: up to 96 FXS ports in a 1U design, with dual Gigabit Ethernet.

FXO Models for Provider Lines

An FXO VoIP gateway connects analog lines from your provider, such as PTCL landlines. Your IP PBX can then use those lines for incoming and outgoing calls.

• Yeastar TA410: 4 FXO ports, with SIP and IAX2 support.
• Dinstar DAG1000-4O: 4 FXO ports, with VLAN and QoS support.
• Dinstar DAG1000-8O: 8 FXO ports, with echo cancellation and a jitter buffer.
• Yeastar TA810: multiple FXO ports, for desktop or rack mounting.

Digital E1, T1, and J1 Models

A digital VoIP gateway suits businesses that receive a digital trunk from their provider, because one circuit can carry many calls.

• Yeastar TE100: 1 E1/T1/J1 PRI interface and up to 30 concurrent calls.
• Grandstream GXW4501: connects E1/T1/J1 PSTN lines to an IP PBX.

Expansion Modules and All-in-One Options

You may not need a separate device. For example, some Yeastar PBX systems accept expansion modules, while one listed model combines both roles.

• Yeastar EX08: adds 8 FXS ports to a compatible Yeastar PBX.
• Yeastar D30: adds digital trunk connectivity to Yeastar P-Series and S-Series systems.
• OpenVox UC501: a compact unit that combines gateway functions with a built-in IP PBX.

VoIP Gateway Features to Compare

• Port count: count your phones or lines today, then allow room for growth.
• Protocol support: confirm SIP support, because your PBX must be able to register the device.
• Fax support: look for T.38 if you still send faxes over your network.
• Voice quality: compare codecs such as G.711, G.729, and G.722, as well as echo cancellation.
• Security: check for TLS and SRTP encryption if calls cross an untrusted network.
• Mounting and management: choose desktop or rack mounting, then check for web-based configuration.

Plan a VoIP Gateway Setup

A gateway is one part of the system. Therefore, your network switches need to carry voice traffic reliably. If you replace an analog phone later, IP phones connect directly to the network instead. You can also review the official details from Yeastar and Grandstream before you decide.
