I am using NowSMS to evaluate its various feature. I am using trasparent routing with two SMPP connections and my message is binary with 8-Bit coding. This allows only 140 characters but if subscriber will send message with more than 140 characters provider charges me for two message. I want to limit the number of characters of any message to 140 bytes when it is going out from Outbound SMPP connection, above 140 bytes all characters should be discarded. Kindly help me.

NowSMS will accept messages longer than 140 bytes binary (or 160 bytes text), and automatically segment the messages for upstream delivery.

(This is done to provide easy support for SMPP clients that can't handle segmentation.)

However, it will log this as multiple messages received (and the accounting callbacks will also indicate this). So even though the client submitted one message, NowSMS would record this as more than one message for your charging mechanisms.

In saying this, however, I am assuming that you have two SMPP connections, one as a client (defined in "SMSC" list in NowSMS), one as a server (defined in "SMS Users" list in NowSMS).

If both are SMPP client connections (defined in "SMSC" list in NowSMS), and you are using the ReRouteReceived setting, then this is probably handled separately.

Tell me more about your configuration, maybe we can come up with a solution, but I think I need to understand the message flow better.
