Sending DLR in case multiple clients binded

Hello,

How to make sure that DLR is sent to client with whom it belongs to? Normally when DLR received here is how i am sending it back to client.

session.on('pdu', function(pdu){ if(pdu.command === 'deliver_sm'){ session.send(new smpp.PDU('deliver_sm', { esm_class: 4, short_message: pdu.short_message.message, source_addr: pdu.source_addr, destination_addr: pdu.destination_addr, receipted_message_id: client.id })); } })

Thanks,

In the end I would not try to look too hard on the session id, because your client could close the connection and reconnect back, in that case the session id would change and you wouldn’t be able to send the DLR back to him

What I’d do instead is

• Every time your client sends a message store it with your client_id (in a ddbb or whatever)
• Store the message_id you received from your provider when sending the message and assign it to your client id
• When you receive the DLR from the provider it has the message_id, so you look for that message_id in your store and you know which client to sent it to

I don’t recommend you to blindly proxy submit_sm and deliver_sm, but develop your solution in the mmiddle to handle communication from/to your client and to/from your provider
