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.
