The Isdn is configured as Pt-&gt;Pt and as well as the main number I have 6 DDI Numbers. Recently due to a business requirement I have had to Request anothere number to be presented to my System via the Isdn line. The line works fine to the system but I cannot configure it to ring on a single extension. I have tried Deleting one of the DDI No's and inserting the new number but still no joy. I think I need the Isdn2 line to be converted to pt-&gt;mpt and reconfigure the System accordingly. However I am usure how to go about this. Can anyone help?</P> Tue, 18 Jan 2011 18:10:14 GMT althenick 2011-01-18T18:10:14Z https://business.forums.bt.com/t5/Archive/BT-Versatility-and-ISDN2e/m-p/20869#M16117 <P>Hi,</P><P>I have a BT Versatility with a Single ISDN2e connection.
