Thank you very much for so helpful advices!
1) and 2) are working well. Tomorow I'll test the fax. I think i have a DISA card inside
What can I do to make faster, calling from telephone (plugged into JACK01) to the external number? In this moment, the connection dure very long... (about 10s)
Should I always put 9 before the external number? Is it possible to to set telephone on JACK01, always calling outside numbers?
