SMPP delivery report

Question

How to check for the delivery report of the sent message. I am using PHP and I have the SMPP account. Can somebody help me with the checking of delivery report?

Will I get a delivery report as message like we get in our mobile?
Or the status of the send function will do for it?

Using SMPP you can retrieve delivery report in the following ways.

First choice is to set registered_delivery parameter to 1 when you send submit_sm PDU.
In this case SMSC should send you deliver_sm PDU with esm_class = 0x04 containing delivery report.

Other way is to request delivery status with query_sm command but this may generate more traffic if polling SMSC too often.

Any example on python? – Gustavo Piris Feb 02 '18 at 14:20
@Gustavo Piris, the language doesn't matter.. just get an SMPP class and apply what he told you, you could think of the first choice as a normal message on phone, you set the reports to on and when the msg is delivered the provider will send you a delivery report. You just read that using the `deliver_sm` command. – bakz Apr 05 '18 at 00:10

SMS delivery receipts are regular SMS text messages generated by SMSC, but esm_class = 0x04 is used to differentiate them. The esm_class = 0x04 means PDU direction is SMSC > ESME and short message contains SMSC delivery receipt short message.

Short message area of deliver_sm SMPP PDU consists below text format which is encoded using dcs=0x00 data coding scheme (i.e. SMSC Default Alphabet according to the SMPP specification):

id:{message_id} 
sub:{message_sub}  
dlvrd:{message_dlvrd}
submit date:{message_submit_date} done  
date:{message_done_date} 
stat:{message_stat} 
err:{message_err}

Sample delivery receipt message text:

id:40072910491427628 sub:001 dlvrd:001 submit date:1007291049 done date:1007291049 stat:DELIVRD err:000

If you're asking about the format in which the Delivery_Receipt will be delivered back to the source then it's carried as the user data payload in the SMPP deliver_sm or data_sm operation.

The following fields are relevant in the deliver_sm and data_sm operations when used for transmitting delivery receipts:

• source address (i.e. source_addr_ton, source_addr_npi, source_addr)
• destination address (i.e. dest_addr_ton, dest_addr_npi, destination_addr)
• esm_class
• message_state
• network_error_code
• receipted_message_id

@Priyanka Hi. I am sorry but since it has been more than 4 years since I answered this question and haven't worked with SMPP for the same amount of time, I really can't remember anything on that topic. :) – Eugene S Jul 28 '16 at 14:12
