DLR Issue - delivery SMSC in TX+RX mode #123

Closed m-faraz closed 4 years ago

m-faraz commented 4 years ago

We are using ksmppd in a production environment (very efficient I need to add and a life saver). We have run into an issue slightly. The setup is as below

client -> ksmppd -> kannel -> operator

The client end SMPP is set using TRX (Transceiver), but the operator end unfortunately is in a TX+RX mode (2 different connections). We are able to receive DLR from the operator, but the same are not getting forwarded back to client.

I am attaching a combined log from all relevant logs. Can you point out any issues here?!

Issue resolved. The client just had to connect to us using a transceiver connection. earlier they were using TX/RX.
