Maybe a channel ordering problem? If you have a 4 port analogue card for example then if that card is detected first you will find it is channels 1-4 and therefore your ISDN30 will be channels 5-19,21-35 and the D channel being 20. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
