	Pros & Cons from Real Users Pros Call forwarding, call transfer, call tracking and the rest of the features of PBX and CRM. I use it on a daily basis for inbound and outbound calls. A very useful service when travelling abroad, allowing you to communicate without breaking the bank. The PBX is very helpful, as it keeps the work running even when I'm not at the office. I mostly use it to make and receive calls, and some features of the PBX, such as voice greeting, voicemail and call recording. Clear Calls: Calls are crystal clear. I haven't had many hiccups, even with international calls. Saves Money: It's budget-friendly. I'm spending less on phone bills since I switched. Packed with Features: Lots of cool features like call forwarding, video chats, and voicemail. It's made my work life easier. Easy to Use: Setting up was a piece of cake. The interface is user-friendly, even for tech newbies. Scales Up: Whether you're a tiny startup or a big corporation, it can grow with you. Add or remove users as needed. The interface and features in the PBX, their own CRM and the integrations with others make it a useful product to combine. They offer telephony services and recently added data for travelers. We're looking forward to the new implementations they plan in the future. It is worth the price. Thank you Zadarma. Calls rates. Calls quality. Their free PBX and CRM. many features for free (voice mail, call forwarding, conference, call tracking ...) Customer service which is always available. Cons Didn't understand how to set up forwarding with the instructions. I have no complaints so far, everything is working flawlessly. Needs Good Internet: It relies on a stable internet connection. Internet problems mean no calls. Emergency Limitations: Not the best for emergencies. You might need a backup plan. Hardware Matters: Some old gadgets might not play nice with it, so check compatibility. Wish they could add numbers from more countries, specially mobiles. No available app for MacOS.
