So what are people using these days for SIP or IAX to PSTN gateways.
1. Do any of the standard companies (Packet8, Broadvox, Vonage, etc.) allow you to use your own SIP device (phone or something like *) instead of the interface hardware they usually provide?
2. What about latency and reliability?
3. Finally, do any of the providers deliver more than one call via SIP? In otherwords, if I'm already on a call and another comes in will they attempt to deliver it?
Thanks
