works for sure in the states... but it's not 100%.. matter of fact only about 70% of the times i've attempted it has it followed through, perhaps due to bandwidth issues? not sure... uhhh... be sure not to put the give the caller id a long name.... maybe 15 characters?...... no space in the number (666-666-6666 is wrong... do 6666666666) and uhh... try it on yourself to test it.. takes about 20 seconds to ring once the xml page loads... cheers
