Re-Requesting Delivery Status

Post by zaffarowais » Fri Jan 05, 2018 9:28 am


Is there any way we can request DLR status of a particular SMSID from our providers, or is it that only the providers can push the status.

P:S I am sorry if I am posting this topic again, tried to search the forum but could not find anything relevant.

You can try to send QuerySm PDU to provider. ... DU_QuerySm_

Code: Select all

QuerySmResp resp = _client.Query(messageId, srcTon, srcNpi, srcAddr);
MessageState state =  resp.MessageState;

Please note, that not all SMPP providers support this PDU type. Please ask before.
