I dont know how usefull this is for you guys, but I was looking for some UK Call Progress tones for the UK for my new Linksys SPA942. I found a World Database that should help some of your guys here: http://www.3amsystems.com/wireline/tone-search.htm once you have selected your country and what tone you require and press Search it will list the frequencies and Cadence for the type of tone you need. then look at the bootom of the table and Select the "Switch to a different display format:" [Sipura/Linksys] or [Zaptel/Asterisk] Hope this helps.
