Mail Plus - Powerful. Affordable. Sign up now. > http://mailplus.yahoo.com The SMPP 3.4 spec is clear about the use of two connections, but offers another type of bind operation, BIND_TRANSCEIVER. This type of bind (over a single TCP connection) may both receive Mobile Originated and Delivery Report messages, and send Mobile Terminated messages. Having two binds (BIND_TRANSMITTER + BIND_RECEIVER) over a single TCP connection is not supported by most SMPP clients and servers. HTH, David WHITE CONNECT AUSTRIA -- David White <[email protected]>
