Both of them come from the same manufacturer, ObihaiTechnologies, which was founded by the pioneers in the VoIP industry. Obihai was purchased by Polycom in 2018, so don’t be surprised if these two names intersect. Anyhow, these devices have a good pedigree.

Because they are all about cheap calls, we’re going to compare them in areas:

  • Connectivity. With so many providers, you would like to have the freedom of choice …
  • Ease of use. Because nobody likes complicated settings
  • Call quality. Because you would like the call to be, besides cheap, of good quality.
  • Value. Savings from leaving your telco operators should not be reduced to much by the price of the device.


OBi200 vs. OBi300: Connectivity


This little device has the possibility to connect you to four VoIP services. And all through one telephone port. ( if you want to connect two devices you would want to buy OBi 202).  So,  you plug in one device- phone, and then you choose your VoIP providers. You can switch between one or the other during use.

Obi200 comes with preinstalledOBiTALK, which enables free calls between Obi users.  It is also Google Voice compatible, which enables free calls inside the USA and Canada. Some premium features like Caller ID, call forwarding, call waiting, 3-way calls, block anonymous calls faxing are available.

There Is a nice selection of wireless and Bluetooth adapters which will enable you to do that.Obi200supports T.38 Fax standard.

This versatility might present a problem. Sometimes it may be just too complicated to connect the device to all of the operators.  Most of the complaints are about problems with the providers. The first connection of the device, despite what they say, sometimes may be frustrating. ObiTalk doesn’t have a call center. They only receive and send emails. That can be time-consuming.

This issue is not exactly a problem with the device itself, but with the providers. However, it can reduce your satisfaction with the device and your overall satisfaction.


It definitely offers less connectivity than with Obi200, because Google Voice service is not supported. It is a Sip service provided product. It can combine OBiTALK with four SIP Voice services. A nice feature is that you can make free calls to any Obi device. It also supports  T.38 Fax standard. It is very simple to set up thanks to zero-touch customization (ZT). It also has a USB port to which you can hook up wireless or a Bluetooth adapter.

The downside to this simplicity is the lack of choice. No Google Voice service,  so you are denied free calls to USA and Canada.
