I don't know what is going on by I keep having phone numbers stop working on my client sub accounts. It started with two client that were on auto recharge and then for some reason the auto recharge failed and put them in negative and their account stopped working, So then we got them in the positive but their phone numbers never started working after that. Then today I have a client that their number stopped working and they never have gone negative on their account so I know that was not the issue. The only thing I can do to get this working is to trash the number and buy a new one. I hope the root problem can be found to this issue.
