We are an independent VoIP provider with our own in-house registrar and softswitches. With multiple customers using the GS Wave Lite - Video app as a client. The voice and messaging is working just fine but I have a few questions about Group Messaging. If I create a group message and send a message, our system receives individual sip messages with a To of one member at a time. EX: I send to two other numbers, we get two messages addressed to each one independently. How do we tie them to the group. What does an inbound group message look like to the Wave app?
