iTalkBB's secrete backup China DID number

One of the features that distinguish iTalkBB from the rest of VoIP providers is the so-called China DID number: your iTalkBB phone comes with a FREE China phone number and your family and friends in China can simply call your local China phone number to reach you in the United States/Canada without having to pay an International call charge! Feel interested? Sign up with iTalkBB with promotion code 953110 to take an additional $10 off.

To call from China, simply dial 17971001+899-xxx-xxxx where 899xxxxxxx is your 10 digit iTalkBB number. In most places in China, this feature has been enabled by the local phone carriers -- see a detailed chart here: http://www2.italkbb.com/bb/enu/enu_support_07.asp

However, if the caller happens to be in a region that 17971001 number is yet open, here is a backup: dial 4007-128-899, wait for it to connect, then dial the 899-xxx-xxxx number, followed by # key.

(A reader of the blog has complained about having a friend in China without direct 17971001 access. Here is your solution then.)
