Re: Lucent G3 PBX connect to VIC-2FXS issue

I see from your topology that you are using a fxs port to connect to your PBX. This is not a supported configuration. The reason behind it is the fxs port cannot pass on the dialed digits out to the PBX. This is the reason you are able to dial in one direction and not from the other side.

You should either connect a FXO or an E&M port with a compatible port on the PBX.
