Is Zoiper Classic 2.43 Better for Modern VoIP?

This is the critical question. While the download is better for performance, there are trade-offs.

The "Better" Checklist:

• ✅ CPU Usage: Less than 1% on idle.
• ✅ Startup Time: Instantaneous.
• ✅ Audio Latency: Lower than modern versions due to simpler audio routing.
• ✅ Firewall Compatibility: Uses standard ports without aggressive UPnP scanning.

The "Worse" Checklist (Honesty):

• ❌ No TLS 1.3: Security is weaker. Do not use this over public internet without a VPN.
• ❌ No OPUS Codec: HD voice requires external transcoding.
• ❌ No Video: This is voice-only.
• ❌ Windows 11 Issues: You may need to run as administrator with compatibility set to Windows 7.

If your priority is security and HD video, do not use 2.43. If your priority is stability on low-end hardware and simplicity, then yes, Zoiper Classic 2.43 is the better choice.
