Your posting is very helpful. Thank you very much.
I have a silly question:
Will it work if I still want to use landline phone? Probably, I need to use OBI 110 to set it up.
Right now, I am using iTalkBB. I would call relatives in China. But I am not happy with iTalkBB and looking for alternative to replace iTalkBB.
Any suggestion, configuration details, etc are greatly appreciated.
