Is C2C Softphone safe?

Low risk

C2C Softphone sends dialed numbers' geolocation lookups to Radar and calls to its own phone API using a hardcoded key.

The extension adds click-to-call softphone features to web pages and connects to the vendor's call servers. When a dialed number lacks a leading '+', it looks up the user's IP location through api.radar.io using a secret API key embedded in the extension code. Its page-level message listener on all sites also accepts login and logout messages without checking the sender, so a web page can set which account the softphone uses.

Shared hosts - 3 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
