#9 is not really accurate. He never said he was testing FXO ports, he was testing the wireless handset by using it as their home phone. FXO ports would absolutely be in the list of equipment used in test scenarios for Cisco VoIP. UCM with SRST is a standard branch application.
Usually with SRST there is a greater need than just 2 ports for PSTN access. As it relates to production systems in Ireland and RTP this is certainly the case. I base this on the thought that any remote branch support within Cisco would be handled by IT and not an alpha system.
