Router B-2811with 2 VIC 4FXS modules installed
Calls are received on router A and forwarded to Router B.
Only 1 line gives a problem when analog phone is connected to the FXS port on router B.
1. No diale tone for outgoing calls
2. Analog phone rings but only calling party can hear the called party's voice.
Called party does not hear naything.
There is no issue for other lines with same configuration setup
