This is actually a pretty simple way to do it, but not as easy as you might think. The following sentences are simple enough, but I’ll have to go through them in more detail.
To call somebody with an extension, you just say the person’s number, then add “9” to it.
So if you have three phone numbers, you could potentially call them all with this method, but unless you know all three numbers or they’re all the same number, you’re not going to get any calls. You could also say the numbers, and then add 9 to the end, but I think adding 9 to the end would be more understandable.
This problem is further exacerbated if the person you’re calling has a mobile phone, since each 9 makes the two numbers sound the same. If that person is on landline, you can use this method, but if he or she is on the phone, you would need to use a local phone number.
This could be a problem for some people. If you’re on a land line with your phone in your pocket, you could also call your landline (and perhaps even your phone company) to see if they’re going to be willing to send you a call.
The reason that people sometimes just use their phone to call for a few minutes is that it’s easier to use the phone to get the number you need to call back. With phones, it’s more convenient to get the number you need to call back.
You could use different numbers. If you have a landline, for example, you could always use a different one. If you dont, you could still call the same number by phone.
If you don’t have a landline, you might just call the company and ask for that number. You could also use a phone number as a way to get your landline to your mobile phone.
But if you dont have a landline, then you may want to call a landline number. Not just because it is easier to reach a landline than a mobile phone, but because landlines are more reliable than mobile phone. And if you dont have a landline, you will have a number of other phone numbers that you can call.
Landlines have a few advantages over mobile phones. When you call a landline, you are guaranteed to reach someone at all, regardless of your location. That may not be true for a mobile phone, but landlines are more reliable and will eventually reach you.
