Hello, I have a problem with 3CX and Linksys SPA-3102 configuration. Actually everything works except the system diverts the PSTN Calls to system extensions. When a PSTN inbound call rings, only the phone which is connected to "Line 1" of "SPA-3102" rings, but not the extensions of 3CX. In 3CX, I have routed the PSTN inbound calls to the extensions but it doesn't work. I'll be appreciate that if I can get some help about this problem. Thanks in advance. PS: The images of the configuration are attached.
