I configured an MGCP Gateway with an FXO port. I created a Route Pattern that when 0 is pressed, it connects to the FXO port and give the PSTN dialtone. Everything works fine, the only thing is that on the display, when I press 0 I get "To Unknown Number". I have 0. in the pattern and I configured it to discard PreDot.
How can I display the dialed number instead on "To Unknown Number"?
Thanks for your help.
