Re: SoftPhone options in India - Virtual phone number for receiving SMS & OTPs International roaming, SMS to email synch are definitely the most obvious and pragmatic choices.
But, back in late 2000s, when I was in US, the days of Magic Jack et al. and expensive VoIp and international roaming calls etc. I would wonder about a cheaper model. My research led me to this idea.
Have two servers on Asterix ( it's an open source EPABX platform), one in India, one in US. Both, connected to their respective mobile networks using those Huawei 3G dongles that supported voice calls, SMS and USSD features. You could set this up in two ways
1. Some one calls you within India on the Indian number, the Asterix server in India bridges the call over to US server which then uses its SIM, or soft phone set up to forward the call to your US number that you have pre-configured.
2. Or if you didn't want to tie up this setup with only one US number, you could set up an IVR in Asterix. If am not wrong those Reliance or Airtel prepaid calling cards that we used back then to make calls to India, used some set up similar to this.
Effectively, you are creating VoIP gateways, on both sides. But, this set-up would have been illegal according to Indian laws, back then. Don't know if they have amended the laws. But, would have been a good project for personal use and the kicks and giggles. Didn't have the time back then, though.
