I have a SPA9000+SPA400 that have been working without problem for a few years. I recently changed Internet service and replaced a SMC router with an Apple Time Capsule. I now no longer hear inbound voice on calls. I have both Linksys IP phones as well as a brand new vtech phone on FXS 2. I suspect this is a NAT issue, but can't seem to identify the proper config option on the SPA9000.
Any advice would be appreciated.
Shaun
