Windows-Based Android SIP GSM Gateway

Hi Asterisk Community,

I’d like to share ApexVoice, a Windows-based Android SIP GSM Gateway solution that converts Android phones (and some GSM phones) into SIP-to-GSM gateways for VoIP routing.

This tool allows users to:

  • Turn Android phones into GSM gateways

  • Route SIP calls to GSM without expensive GSM gateway hardware

  • Integrate with Asterisk / FreePBX / SIP servers

  • Use USB or local phone connection (no Bluetooth complexity)

  • Manage multiple phones as a scalable low-cost GSM gateway pool

  • Perform call termination, SIM routing, and mobile call bridging

It’s useful for:

  • Call termination setups

  • GSM fallback routing

  • SMS/call gateway experiments

  • Labs, small VoIP providers, and budget-friendly GSM routing

  • Testing SIP ↔ GSM interoperability

If anyone here has tested ApexVoice with Asterisk, I’d love to hear real-world feedback on:

  • Call quality & latency

  • SIM stability

  • Concurrent call limits

  • Production-level reliability

Thanks — hope this helps others exploring software-based GSM gateways on Windows!

Do you have a Linux version?

That way, everything can be done on one server, instead of splitting it across two.
