Commands to receive SMS with SMPP

[Tricia]

Which SMPP commands are communicated with the SMPP provider to send/receive a message? Can I see a log of all operations?

Yes, you can see all commands using a trace file. By default, tracing is NOT switched on. Tracing is enabled/disabled per channel.
You can enable tracing for SMPP by specifying a log file for the particular channel in the registry:
HKLM\Software\ActiveXperts\SMS Messaging Server\Trace\SMPP.xxxx ,
where xxxx is the actual channel number.
After you change this registry value, you MUST restart the SMS Messaging Server engine (service) for the changes to take effect.

What about the SMS and Pager Toolkit SMPP? I know about the Logfile, but it is not quite detailed. In my case I got a problem to connect to the SMSC via SMPP and the only Logs I get are:

[17:05:45] CONNECT [SMS and Pager Toolkit Build 4.1.7.0809], Server=[198.228.90.xxx:81yy] , SystemID=[GWIN_APPSR131], SourceTON=[7], SourceNPI=[66], AddressRange=[], Result = [23201 : Unable to connect to host]

As you can see, I have no clue whether the the SMPPClass has sent "bind", the Firewall blocked or a parameter is missing. If there would be a possibility to LOG the SENT / RECEIVED Transaction-Log, I'm sure it would be very helpfull.

Is there a way how to do so?

Hi,

It is not possible to do some more logging when no connection can be made. Please check your firewall settings.
