    Hi Gary,

    You did a great job with this article. I have a little problem with an ISDN line that has 2 numbers. How can you make an S20 to manage the 2 numbers (ie. 0438111111 and 0438222222). When an outside call gets the ISDN line, number 0438111111 has to make ring a calling group, and number 0438222222 has to go to extension 210. I tried with DID but didn't work. Do you have any idea? Thanks.

    Best regards,

    Walter De Stefano.
