Today, the telephone service provider camp. Competition in service. Provide promotions. We have to choose. Some camps offer free calls 24 hours a day, but they can be up to one hour at a time. If you think about 2 baht a minute.
The problem is that users often call and wait more than an hour to make more expensive call charges. Today admin has an app for setting. Or set the time to call. How many minutes can we make a call? The system will cut it for ourselves, such as we want to call no more than 1 hour, we set this app at 59 minutes, at 58.55 time, the system will cut us.
Good to go again. Can be cut when there are other calls.
We did not cut off the call.
