Description
Been using Groundwire: VoIP SIP Softphone for a couple months now. It’s basically a SIP client app that lets you make high-quality voice and video calls over the internet. Pretty solid app if you’re into that kinda thing.
Here’s what you do: you can make calls, transfer calls, put people on hold, all that stuff. There’s also a nice address book where you can save your contacts. And the call quality is really clear – I’ve noticed a big difference compared to some other softphone apps I’ve tried.
Look, if you need a reliable SIP softphone for work or personal use, you’ll probably like this. It’s not perfect – the interface can be a bit confusing at first – but overall it does the job. Worth checking out if you’re in the market for a new VoIP app.
Editor Opinion
So here's my honest take on Groundwire: VoIP SIP Softphone. I've tested a bunch of VoIP apps and this one's pretty solid. The call quality is really impressive - crystal clear audio and video. It's also got a nice set of features like call transfer, hold, and an address book. The interface isn't the most intuitive, but you get used to it after a while. My only other complaint is that it can be a bit glitchy sometimes, but that's not a dealbreaker. Overall, if you need a reliable SIP softphone, Groundwire is definitely worth a look.
