We are still in contact with our provider who are working hard to get the number restored to service. They should have a resolution for us by the end of the week. In the meantime we are actively looking for another carrier to provide us with a replacement local number for China should this issue continue past the planned resolution date.
We have temporarily disabled sending out the problematic number on email invites. If users do not wish to use our World Wide number they should consult our international numbers list and choose a number appropriate to their location: https://meetupcall.com/numbers
