parsing SMPP deliver_sm PDU with optional parameters

[orxanx]

Dear friends,

 

I have wrote bulk sms application with php for my job, and I have used some php classes which I found on net.  When I send sms by class , he sent sms(submit_sm) successfully, and received delivery (delivery_sm) too. But not parsed optional parameters delivery_sm PDU.

 

I have attache, php script which I receive delivery reports. Please check it for me. If it's possible parse optional parameters to, let's do it together.

It's is necessary for me, because I will report status submitted sms. Optional parameters like this with dump WhireShark.

 

 

Optional parameters

        Optional parameter: message_state (0x0427)

            Tag: 0x0427

            Length: 1

            Message state: DELIVERED (2)

        Optional parameter: receipted_message_id (0x001e)

            Tag: 0x001e

            Length: 9

            SMSC identifier: 4D17A644
