Hi Hugh, 

Thanks for you help, 3CXphone is good to use and free one, however the vendor  has also SIP server which competing with FS, 
i'm looking for a free sip client for iPhone for my users which will  not involve competition with FS... like CSipSImple on Anroid, it as only client not server which is safe for my project that will not involve sip server vendor to compete, if you know, please kindly advise, thanks a lot!

Regards,
Charles

Hello -

I've used both 3CX and Acrobits:

       http://www.3cx.com/products/3CXPhone-for-iPhone.html

       http://www.acrobits.cz/4/acrobits-softphone-for-iphone

3CX is free, while Acrobits is not, but Acrobits has more features.

Both work quite well.

regards

Hugh
