I'm having a similar problem. The difference is that we have one cluster, three office sites and multiple home users. We just recently implemented a subnet at the main office, where Call Manager resides, with the intention of putting the phones on that subnet. The problem is that, when a home user calls a test phone on that subnet, there is no voice traffic either way. However, when someone using the test phone calls a home user, everything works fine. Calls from either of the secondary office sites work fine both ways. We are using a PIX 515 in the main office and Cisco 831s in the home offices. Does anyone have any suggestions?
Thanks for any help provided,
