Should I bing with transceiver or transmitter/receiver?
SMPP defines three modes of operation for an ESME: transmitter, receiver, and transceiver.
When connecting to Vonage SMPP API you should select one of these modes of operation:
- Transmitter/Receiver Mode: Transmitter will enable you to submit messages, and query the status of messages and system parameters, but it is not able to receive messages or delivery receipts (DLR). To receive DLR and inbound messages, you need to also bind as a Receiver.
- Transceiver Bind: SMPP version 3.4 introduced the transceiver type of connection. It is similar to having a transmitter and receiver connection over the same network link and allows submitting and receiving.
We suggest using transceiver bind when possible as it helps to maximize the amount of network links (connections) available for your account (by default is 2).
