IdeaSIP worked fine for me when I had the same need some months ago. 
Asterisk config snippet:

[ideasip-tollfree]
; USA toll-free
exten => _001800NXXXXXX,1,Dial(SIP/${EXTEN:2}@proxy.ideasip.com,60)
exten => _001888NXXXXXX,1,Dial(SIP/${EXTEN:2}@proxy.ideasip.com,60)
exten => _001877NXXXXXX,1,Dial(SIP/${EXTEN:2}@proxy.ideasip.com,60)
exten => _001866NXXXXXX,1,Dial(SIP/${EXTEN:2}@proxy.ideasip.com,60)
; UK toll-free
exten => _0044800.,1,Dial(SIP/011*${EXTEN:2}@proxy.ideasip.com,60)
exten => _0044808.,1,Dial(SIP/011*${EXTEN:2}@proxy.ideasip.com,60)
exten => _0044500.,1,Dial(SIP/011*${EXTEN:2}@proxy.ideasip.com,60)


00 is the ITU-recommended international prefix (used in Germany). For 
Taiwan, you might want to replace it with something else, e.g. 019 (note 
the change in EXTEN because the prefix length increased):

[ideasip-tollfree]
; USA toll-free
exten => _0191800NXXXXXX,1,Dial(SIP/${EXTEN:3}@proxy.ideasip.com,60)
exten => _0191888NXXXXXX,1,Dial(SIP/${EXTEN:3}@proxy.ideasip.com,60)
exten => _0191877NXXXXXX,1,Dial(SIP/${EXTEN:3}@proxy.ideasip.com,60)
exten => _0191866NXXXXXX,1,Dial(SIP/${EXTEN:3}@proxy.ideasip.com,60)
; UK toll-free
exten => _01944800.,1,Dial(SIP/011*${EXTEN:3}@proxy.ideasip.com,60)
exten => _01944808.,1,Dial(SIP/011*${EXTEN:3}@proxy.ideasip.com,60)
exten => _01944500.,1,Dial(SIP/011*${EXTEN:3}@proxy.ideasip.com,60)


So if you dial 019-1-800-whatever, asterisk will connect to 
sip:1800whatever@proxy.ideasip.com.
HTH.
