SMPP SMSC Simulator

smpp-smsc-simulator

This code was previously used in an early version of the Melrose Labs SMPP SMSC Simulator service. The SMSC simulator (or SMPP simulator) is used to test an SMS application's support for the SMPP protocol and to simulate the delivery of SMS.

Build

g++ -std=c++11 smscsimulator.cpp -o MLSMSCSimulator 

Run

./MLSMSCSimulator

The SMSC will listen for connections on port 2775.

If you wish to use TLS with the SMSC simulator, then you should put an AWS load balancer in front of the server on which you run the simulator or use openssl to bridge to the SMSC simulator.

Docker

Alternatively you can build and run the SMSC simulator in docker

docker-compose up

This will build and run the SMSC simulator in Docker on port 2775.
