I see it's been a while since this was posted, but I just wanted to ask—has anyone tried using current open-source SIP clients like Jami or Linphone lately? Curious how they hold up for call quality and reliability compared to paid services. Also wondering what setups people are using nowadays for securing VoIP—any simple tools you’d recommend for encryption or traffic monitoring?

Tested this for a few clients lately—call quality held up great even with high traffic. Setup didn’t take long, and it’s easy to manage even without deep tech knowledge.
