SMPP using WSO2

Question

Hi Followed the blog mentioned in SMS Transport sender in wso2 ESB and configured axis2.xml for transportSender and transportReceiver. I am able to send a message from ESB to SMPP simulator but I am unable to receive message from SMPP simulator to ESB.

In the SMPP Simulator, I tried by adding bot 't'/'r' to enable transmitter/receiver and also tried by giving tr assuming that it is for tranceiver in users.txt but still I am unable to get a response in ESB.

Could you please help in implementing SMPP -> ESB scenario. Any link that describes this procedure also helpful for me. ( I am unable to find such)

I am editing this to make my scenario more clear

My simulator is opensmpp-sim. I added the user details in user.txt as name=esb password=esb timeout=unlimited bound=t,r

I executed the simulator with port 2775.

In ESB, axis2.xml I gave the following configurations Transport Receiver

<transportReceiver name="sms" class="org.apache.axis2.transport.sms.SMSMessageReciever">
    <parameter name="systemType">cp</parameter>
    <parameter name="systemId">esb</parameter>  
    <parameter name="password">esb</parameter>
    <parameter name="host">192.168.0.2</parameter>  
    <parameter name="port">2775</parameter>
    <parameter name="phoneNumber">94777179968</parameter>
</transportReceiver> 

Transport Sender

<transportSender name="sms" class="org.apache.axis2.transport.sms.SMSSender">
        <parameter name="systemType">cp</parameter>
        <parameter name="systemId">esb</parameter>  
        <parameter name="password">esb</parameter>
        <parameter name="host">127.0.0.1</parameter>    
        <parameter name="port">2775</parameter>
    </transportSender>

Note: 192.168.0.2 = 127.0.0.1 = localhost

Scenarios 1. Sending a message from ESME (ESB) to SMSC (Simulator)

Sequence

<sequence xmlns="http://ws.apache.org/ns/synapse" name="TEST_SMS">
   <send>
      <endpoint key="SMSC"/>
   </send>
</sequence>

Endpoint

sms://94777179968

I exposed this sequence as a REST API. When I send a message, the message reached Simulator but there is no response in return.

2. Sending a message from SMSC (Simulator) to ESMC (ESB) From simulator when I send message, it reaches ESB. In debug mode the message is printed in ESB log. But I am unable to handle it. How can I configure proxy service/ sequence to get that message. My goal is to get that message and initiate a process.

Thanks in advance.
