I have a sip box with two FXS ports (Draytek 2600v adsl router) I have had very little luck getting the two talking together. For a very short time I did have calls originating on my FXO card routed to the phone working. Phone1/2 on router ---> handytone works handytone ---> router phone1/2 works Phone1/2 on router ---> asterisk broken* asterisk ---> router phone1/2 broken** * Can see asterisk receive the number and start following calling plan but no sound comes through, phone eventualy times out. ** Worked for a short time for no apparent reason, now sees phone as bussy, phone does not ring.
