Can we have option to disable sending the delivery_sm_response back to the SMSC?

Hi,

That would break protocol.

What exactly are you trying to accomplish?

A transmit only connection?

There may be a solution that does not break protocol that I can recommend if I can understand what you are trying to accomplish.

Scenario - In case of a network issue that deliver_sm from smsc doesn’t reaches ESME ( nowsms client) I.e we don’t get the deliver_sm_response from nowsms client than we put the deliver_sm in a queue to retry it again after 5 seconds.

Our smsc only supports TRX mode

We want to mimic and test this behaviour.

Hi,

There is actually a hidden setting that we use for testing this scenario, use at your own risk, as it can cause problems for connected servers. The following settings can be applied too the [SMPP - server:port] section of SMSGW.INI:

BlockAllDeliver=Yes
IgnoreReceivedMessages=Yes

BlockAllDeliver=Yes - message is ignored, and deliver_sm_resp is NOT sent

IgnoreReceivedMessages=Yes - message is ignored, but deliver_sm_resp is sent

Hi,

I've sent BlockAllDeliver=Yes, still we've received Deliver_SM. PFA of the smsgw.ini.

The setting in question blocks NowSMS from generating the deliver_sm_resp.

If you are trying to block a deliver_sm, then we need a more complete description of the message flow so that we can understand.
