My NowSMS is connected to broadband SMPP gateway, and also acts as SMPP server. All Submit_SM requests to this server are routed normally to the gateway. Submit_SM requests have Registered flag set to 1, which should bring back delivery reports for each submitted message.

The problem is that NowSMS SMPP server doesn't pass deliver reports to it's client, however it successfully gets them from the gateway (I can see this in log files).

Could you please advise something to solve?

This may happen if the connection type wasn't properly matched with that of the SMSC.

I suggest that you ensure that port numbers for their transmitter and the receiver match those specified on your side.

If you are connected upstream as trx the connection type on the carrier side should also be set as trx, with send/receive ports matching those set up on your side.

Also, this error might happen during startup if you shutdown and immediately start back up.

Some SMSCs are slow to release a session and won't let you reconnect until the SMSC releases the previous session.

NowSMS does all it can to gracefully disconnect when it is shutdown, but I have seen some situations where SMSCs are just slow to release.

So that is one possibility.

It is also possible that your provider wants you to connect as a "transceiver" for sending and receiving messages.

By default, with an SMPP connection, if you check "Receive SMS", NowSMS will establish 2 connections to the SMS service provider, one for sending and one for receiving. This can result in some errors with providers that only allow a single session and expect you to use "transceiver" mode (single connection) for sending and receiving. There is a configuraton option under "Advanced Settings" when you define the SMPP connection in NowSMS for enabling "Transceiver" mode.
