Is it possible to connect a number to an SMPP gateway?

Question

go

Task: when clients send SMS messages to a certain number, they must be recorded in one system. Through this system, you can respond to written clients.

The project was decided to be done over the SMPP protocol (it seems that it was set up on camel). Before with the similar protocol did not work. I found one library on golang, looked at different pdu's for sending messages, for accepting and realized that in all of them work is done with the gateway directly, but in the task, it is necessary that clients not send messages directly to the gateway, but to a dedicated number ( technical support).

Question: Does SMPP (camel) provide for the connection of a phone number from which all received sms will be caught?

Thanks in advance.

Answer 1

A phone number is an entity associated with a mobile operator. In the case of a regular phone, when sending SMS, the operator sends it to you by air. If this is some kind of short number, SMPP integration is usually used, with the help of which all messages get into your software.
The short number must be registered with the operator, and this is money. Moreover, different operators have the same short numbers, these are different numbers and separate money.

Answer 2

In SMPP, there is no connection to phone numbers at all. You can send and receive messages with any digital or alphanumeric signatures.
But in reality, of course, you have to choose from what operators allow. And operators for such a case allow one of two things:
1. A short number to which you can receive messages and from which you can send messages. It is expensive and must be rented from each operator separately (at the same time, checking with all the necessary ones the possibility of renting the same number - it may already be busy somewhere.
2. Federal number to which you can receive messages, but from which you cannotsend messages. It costs less (but still decent), plus it is enough to rent from only one operator that you like more, the rest of the operators will send messages to it as if it were a regular subscriber of this operator.
In 2021, SMS is a very unpopular service. Expensive and inconvenient. I would try to dance from the task and look for ways that, if possible, have nothing to do with SMS. For example, if these are calls for support, then it is better to accept them in instant messengers. Fortunately, now more or less all popular ones allow certain integrations.
