角色 Ching, I have one Obi110 in China, Obi202 in HK & Obi202 in Macau. How can use Obi202 call to China lane line through Obi110? Please let me know the setting and dialing string in Obi202. Many Thx.
Your problem has been answered in Obihai forum. You have to add Obi202 in Macao and in HK to be the Circle of Trust of Obi110 in China. For details, please see Obihai forum.
