Overview

A third-party application is having issues trying to send messages with MSISDN as the title. The SMSC blocks it.

 

Workflow

Instructions

Capture SMPP trace and analyze

Capture the SMPP trace of the issue: Execute the following command as root user on each of the Traffic Elements:

tcpdump -i any port 9500 -s0 -w /var/tmp/`hostname`_Test.pcap

After the test messages are sent, you can stop the capture with ctrl+C.

Open the trace using a tool like Wireshark to analyze it.

 

Fix data coding configuration

Check for a data coding configuration issue, as resolved in this solution article.

 

Contact Support with relevant logs

If it is not a data coding configuration issue, submit a support request with all the following information (from the Traffic Elements, not the MGR):

• /var/log/messages  
• /usr/TextPass/etc/<hostname>_config.txt

• A tp_walkalloutput

• Traces from all traffic nodes as already explained above.
