Hi guys, I'm configuring a Quadro 4L and can't seem to get the IP phones working. They register fine and get their extension. But I can't place a call to other IP phones in the same system.

One gets ext.13 the other ext 14, if I dial the extension 13 from the 14 extension, i get a message that ""there is no one available to take your call...".

The IP phones/lines can place a call to outside pstn and to the other 2 FXS extensions.

Any ideas?

I;m using snom300 phones...
