Thank you for your kind words.

No example afaik but it should be a trivial thing to achieve. If you look at the tutorial configs all we exchange with Opensips or FreeSWITCH is string information so what you populate in should not matter. As I see it you can take 2 approaches for IP auth:
* IP address should become your account in CGRateS
* Use aliasing to convert between IP you send and a real account in CGR.

This was a sample of LCR channel variable however we did not complete testing the idea. Should in theory work but again did not test it. For now your best shot would be querying CGR API for LCR and selecting the gateway in dialplan based on info received from CGR. You will receive simple string tags identifying your suppliers in CGR and you need to match that info within your dialplan logic. I hope I will find the time to finish also the channel vars idea at some point.

This does not relate to CGR since we don't enforce any routing for you. We simply return info which you should use (or not) in your dialplan.

> Freeswitch / OpenSIPs - do we have actually anything better with Freeswitch (doing RTP natively) compared to OpenSIPs with multiple RTP Proxy servers in wholesale system? Freeswitch comes with many features which are totally out of scope in wholesale (voicemails, conferences, etc) so OpenSIPs as a session manager with external RTP Proxy server(s) would actually bring more power and better flexibility in terms of scaling up the platform? Am I correct with this assumption?
More or less. You can also use FreeSWITCH as a dumb b2bua without involving any of the AS functionality. Since OpenSIPs is not a b2bua it is not really recommended that you do accounting there, but we don't live in an ideal world anyway.
Feel free to come back with additional questions.
