In terms of direct-interfacing asterisk with the telco, this means having asterisk config files checked by telco's engineers (AND THE INSPECTION COSTS A LOT!!!). The aforementioned sip-proxy is certified-compatible with the telco and effectively eliminates the need for inspection.

Yes, it's a problem so easy to solve in principle but not so in reality.
