sent and delivered events fired for same sms multiple times

[poonamkumariasp]

I am facing another issue now. I am getting sent and delivered events fired for same sms multiple times.
How can I stop that? How to tell the server that i have got it and please stop duplicating now.

Please help.

Thanks a lot,
Poonam

When the SMS is long (> 140 for ASCII, > 70 for Unicode) it is fired for every parts.

It is happening for short sms also.

Sorry for late response, I tried it and it's work normally as expected. I'm not sure but I expected you are registered with events multiple times.

Hi Adham,
I spoke to my sms provider. They said i need to send them an acknowledgement once I read the delivery notification. Currently, I am not sending them any acknowledgement that's why they keep sending me delivery notification multiple times. If possible can you please provide an example here on, how to send acknowledgement to the sms server. They need DeliverSm.

Thanks,
Poonam

I'm not sure what they need. What is the command and parameters they need?
If they want a response for DeliverSm the SmppClient generate a response for them already and sent it to sms server.
If they want a custom command you can Inherits SmppClient and write a method to send a command they want, see SendMessage method

Hi Adham,

They want something like this: Deliver_sm - resp, Status: "Ok", Seq: 58.

They need this as an acknowledgement of message delivered or message sent notification..

For your reference:
Operation: Deliver_sm - resp (0x80000005)
Result: Ok (0x00000000)
Sequence #: 58

Thanks,
Poonam
