GSM-gateways Elgato are universal telephony devices. They can be used not only for converting GSM to VoIP but also for mini-PBX tasks.
For example, IP-PBX Asterisk can be installed on gateway and set up for dozens concurrent calls. Following video shows what happens to gateway (24 channel model) when making 24 concurrent calls from SIP to GSM.
Test conditions:
- 24 concurrent calls, codec G729 and G711A
- every call makes real load: outgoing traffic is generated by audio-file and incoming traffic generated by auto-responder of mobile operator
- GSM-gateway system resources load is traced with Linux-utility TOP installed on the same gateway
- calls quality is evaluated by software StarTrinity SIP Tester by various jitter statistics
- Asterisk started in «directmedia» mode, NO voice recording on Asterisk is performed
