Calling China Regulations

Hello All,

This may or may not apply to you but if you deal with China its good to know the following

There are China guidelines when traffic hits their country.

· No repeat A number calls.
· No Invalid or restricted A number. A number should be as per E.164 format.
· No random B number calling.
· No China to China.
· No modified/spoofed A number, CLI has to be displayed as originated.
· Unusually high level of calls to unallocated numbers, showing machine generated calls.
· Unusually high level of disconnect initiator release code = 2, meaning called parties hanging up.

If you triggered any of the above you may see an “internal server error” in your FlyNumber Call history
