Hi, I do what you require, but with IAX trunks. I.e. Call comes in from voiptalk.org to my asterisk box. It tries my desk phone, if i don't answer in time, it forwards teh call to my mobile. If you're interested in teh extensions.conf entries for this, let me know,.... i'll post them. Thanks David. -- David Goodwin http://codepoets.co.uk/
