A majority of messages are exchanged via IP and a minority are via SS7. But yes all carriers interconnect via SS7 however many also connect simultaneously with SMPP for intercarrier routing.<br><br>The aggregator I work for does a couple hundred thousand via SS7 per day and 1.5 billion via IP using SMPP/UCP etc per day.<br>
