ToySIM Endpoint Emulator

Lining up dozens of IP phones just to run a quality test? Sending staff to remote sites for manual call checks? There’s a better way. ToySIM emulates endpoint devices (IP phones, HTTP clients, FTP clients, and more) in software, so you can verify quality and performance under real-world conditions without the physical hardware.

Why ToySIM

• IP phone emulation: faithful SIP/RTP reproduction lets you verify call quality and network impact without real handsets.
• Custom scenario design: define call patterns, timing, and simultaneous connections to match how your network is actually used.
• Automated scheduling: set it and forget it. Run tests automatically overnight, on weekends, or at regular intervals.
• Regular quality reporting: emulate IP phones and generate scheduled quality reports for continuous service assurance.

What it solves

• Quality testing across many sites eats too much staff time.
• Realistic load testing is needed, but assembling real handsets is expensive.
• Network changes should be verified before they reach production.
• Routine quality checks should be automated.
