Free Softphone from Portsip

Written by 

PortGo Free Softphone Last year I reviewed three alternative free softphones for Onesuite VoIP service and Pangolin is one of them. PortSip made an improvement to its softphone and renamed it PortGo. Visually it looks the same albeit for the name change. Features-wise it stayed the same but I think it has less bugs and overall experience is improved.

PortGo is built based on PortSIP VoIP SDK, allowing users to enjoy multimedia communications in a dynamic way.

Softphone Features

  • Call waiting – Feature supported
  • Caller ID – Functioning on both ends
  • Voicemail Message Broadcasting – Working
  • Voicemail Forwarding – Works (though this is not softphone dependent)
  • Conference calling – Supported and you can also switch between two calls.
  • Hold – Supported
  • Multiple calls – Allows 2 simultaneous calls, one incoming and one outgoing or both incoming and both outgoing.
  • Auto Answer – Automatic answer after one ring
  • Record feature – You can record conversation instantly.
  • DND (Do not disturb) – It’s like turning your softphone off.

Featuring an intuitive interface, PortGo is expanding the softphone experience by making it even easier to make VoIP and Video over IP calls, see when your contacts are available and send Instant Messages. PortGo features an IM interface which focuses on your contacts and friends. PortGo also provides video conferencing in sip environment. This allows you to manage your communications more conveniently and according to your personal preferences. I made some test calls with my own Onesuite Account and all of my calls are good. The sound is clear and crisp and the intuitive interface is very user friendly. Installation is very easy. Just download the PortGo installation file and unzip it. Run the exe file and just follow the instructions. After installing, launch it and type in your Onesuite SIP info.

ProtGo Login

Username: onesuiteusername-voip.onesuite.com Password: SuiteAdvantage 8 or 10 digit password Proxy Server: voip.onesuite.com Port: 5060 Now you are ready to make your VoIP call.


PortGo Softphone Additional Settings and Configuration Procedure: Right click on the upper part of the soft phone and choose Options for changing Audio Codecs and Audio Set Up for changing Audio devices.

PortGo Settings

Go to Audio Codecs and make sure G.711 uLaw is one of the selected codecs. Click Apply then OK



When using a USB headset, make sure you choose the USB headset on the drop down menu. Click OK when done.


As you can see, PortGo installation and set up procedure is easy and it’s interface is simple and straightforward. I find PortGo as one of the best free softphones around.

    Do you by chance know if PortSip is still in business, I purchased a large quantity of the portgo softphones and they are not responding I think I may be out of luck?

    Hi Pontiac,

    Thanks for sharing. Actually we are going to release a new version of OneSuite softphone very soon. The new OneSuitePhone is also compatible with both PC and Mac.

    We will keep you posted.

    I have downloaded PortSIP SDK and compared it with another SDK called Ozeki VoIP SIP SDK (voip-sip-sdk.com). The usage and functionalities were quite similar. Both of them can be easily used. However I found that the PortSIP VoIP SDK reaches the functions via DLLImport whereas Ozeki SIP SDK is a pure .Net solution. To sum it up I would prefer the Ozeki SDK because thanks to .Net it is more flexible and I could easily implement it into my application.

    Hi Valerie,

    Welcome to our blog!

    Codec is actually a way to encode or decode a digital stream or signal. For more details please see http://en.wikipedia.org/wiki/Codec

    Happy calling!

    I'm new here and learning. So please pardon my ignorance. What is a codec? Is it the interface between the phone and pc?
    I didn't even know you could get a soft-phone, much less actually being such a thing.
    Thanks for any replies you may be generous enough to give me.

    I am not sure if G729 comes free with the old Pangolin softphone but you can still get G729 codec for the paid PortGo softphone.

    free Pangolin 5.3 comes with g729 codec, but they took it out from free PortGo

    Sometimes your number will or will not show up if you are calling an international number. This depends on the carrier/s your call is routed to.

    If you are calling US or Canadian numbers then please notify our customer service @ 1-866-4178483 about your problem as this issue isn't softphone dependent.

    I downloaded PortGo and it worked. But is there a way to show a number other than 1-000-000-0001 on the receiver's phone?

    Thank you for sharing. I downloaded and installed it on my PC and it worked. Very simple interface and so easy to install and run. Recommended for non techie people.
