I found that in India analog lines are all centrex lines and I am having trouble getting the centrex lines to work with the VIC2-4FXO card. I have a 1760v router with VIC2-4FXO and VIC-2FXO and for some reason the centrex lines can only work with the VIC-2FXO. I am not able to get them to work with the VIC2-4FXO. When I dial the number with the centrex lines connect to the VIC2-4FXO card, the call just keeps ringing and I am not seeing anything hitting the gateway. But it works fine with the VIC-2FXO card.
Has anyone run into this type of issue in India ?
I appreciate any inputs/suggestions !!
