GSMCalls: Three Routes from Mobile Phones to SIP
A cloud-managed GSM–SIP gateway platform connecting mobile phones to SIP systems through wired USB, Bluetooth, or a Smart Bridge.
- For
- Telecom operators and SIP integrators
- Worth noticing
- Bluetooth support is explicitly conditional on phone-model and operating-system validation.
Field notes
The comparison distinguishes a local, wired gateway-computer setup from Bluetooth pairing and a per-phone Smart Bridge. The latter is described as using USB-C with charging pass-through and sending audio over Wi-Fi or mobile data. Compatibility is not presented as universal: Wireless Connect support depends on model and operating-system validation. Documentation links cover installation, SIP configuration, device profiles, prepaid billing, and troubleshooting.
