I have not uploaded my own music, just default category is loaded which works fine when draytek is used. when I try to put a call on hold with sipura nothing happens. I can't find the post on freepbx.org because I forgot my password and recreated a new account, but someone said it could be codecs which I tried changing without luck; must say I was worried that with my limited knowledge I may stop other parts od system working when making changes with codecs.
I purchased new phones without success and as it works with another adaptor device, believe it's either a setting on sipura or freepbx.
