number of calls can be made in a month
I need to know more details such as how many calls your products are capable of making each month.
It depends on how long your mesage is going to be and how many hours in a day, and number of days you want to call in a month.
For example, for a 30 second message, you can make 1 call per minute, 60 call per hour, 600 calls for a 10-hour day, and 3000 calls in a 5-day week. For a month, you can make about 12000~13000 calls a month with single phone line. If you use 2 phone line, the call volume doubles, that’s 24000~26000 call per month. And so on.
