How do I get two lines enabled on an analog phone connected to a vic3 4fxs/DID in a 3845 router?

I currently have one line enabled only. I did not do the configuration for that line, and the person who did has left the company. How do I enable the second line? There is no power going to the second line (no lighting of light on phone for line 2) and there are 4 lines in the phone wire.

Thanks for your help

Could you post the configuration?  Is this an h323 or MGCP gateway? 

The FXS ports won't light up unless the port is active (off-hook) so it may be working.  If I can see the config I should be able to help further.

    Here is what I currently obtained. Let me know if you need to see more. The light I was talking about is the one on the phone itself. I do take it off hook on both lines. It only lights up and gets dial tone on line 1.

Config data:

voice-port 0/1/0


voice-port 0/1/1


voice-port 0/1/2


voice-port 0/1/3

The VIC3-4FXS is intended to support a single phone per port.  While you could technically share the same pair for two phones, this would not be ideal.  The best way to handle this would be to use another port on the card, if available.

You may be thinking of the old VIC-2FXS cards where you could have a line1/line2 on port 0, but I'm not aware of any other card supporting two lines on a single port.

Hi Drew,

This sounds like more of a physical/wiring issue than a config issue (perhaps )

On a two-line analog phone that has a 4-wire cord they usually pin-out as follows (on cord);

Green - Tip line 1

Red - Ring line 1

Black - Tip line 2

Yellow - Ring line 2

So you need to to get the line 2 circuit from the FXS to the cross connect panel & to the jack that the

phone plugs into (probably on the White orange/orange white pair in the jack) this should then connect to the Black/Yellow of the 4-wire line cord to supply line 2 to the phone.

Does this make any sense?

A quick way to test this is to take the device that is connected to the "working" port and try it in the other ports.  See if the problem follows the device or stays with the ports.
