Frequently Asked Questions

Everything you need to know about our downloads.

You can download the latest, stable versions of the world's most popular and trusted SIP softphones and dialers absolutely free. Our library includes MicroSIP, Zoiper 5, 3CX Phone System, SessionTalk Softphone, and MizuDroid.
Yes, absolutely! These applications support standard SIP protocols. Even if you use an IP number from another Bangladeshi IPTSP (like AmberIT, BTCL, or BDCOM), you can easily configure your credentials in these apps and use them for free.
For Windows, MicroSIP and Zoiper 5 are highly recommended. They are extremely lightweight, consume very little RAM, and won't slow down your computer even when running in the background. They are the top choices for call center agents.
For mobile devices, SessionTalk Softphone and MizuDroid SIP VOIP Softphone work exceptionally well. They are optimized to provide crystal-clear voice quality over both Wi-Fi and mobile data (4G/5G) networks.
Yes, 100%! You do not need to invest in expensive hardware. Your agents can simply install these free softphones on their laptops or smartphones, plug in a headset, and handle professional call center operations seamlessly.
Setting up is very simple. Once installed, go to the app's account settings and enter the four details provided by your telecom operator: SIP Server/Domain IP, Port, Username (Extension or Phone Number), and Password. Once saved, your dialer is ready to make calls.
Yes. Popular desktop softphones like MicroSIP and Zoiper offer excellent local call recording features. You can easily record customer conversations directly to your computer or mobile storage for future reference.
Modern SIP apps (like SessionTalk) support Push Notifications. This means the app goes to sleep and doesn't drain your battery continuously in the background, but the moment an incoming call hits the server, your phone instantly wakes up and rings.
Downloading software from unverified third-party sites carries a high risk of malware and viruses. At epbx.bd, we host 100% virus-free, tested, and the latest stable releases of these softphones to ensure your corporate data remains secure.
Yes! Even if you are using another telecom provider, our community and resources are open to everyone. You can visit our "Knowledgebase" and "Video Tutorials" pages for step-by-step guides on how to configure each specific app.
