C# interface to a Alcatel-Lucent OmniPCX Office system

[G-HART]

Hello,

I'm trying to create an interface that will allow my Company's software to interrogate the phones, change their status etc as well as record calls logged for bill purposes.

While the O.L.D driver is I metering mode, I have created an application that monitors TicketCollecotr.xml, and pulls the information out.
What I need to do now is expand on this, so that when the driver is in hotel mode, I can get the call data, but also send Handset commands ( changed the name on the display, block/unblock the handset etc .

with the code (below) and the driver in hotel mode, I can make a connection to port 2561 and send data, but I get no response back. On looking at the log.txt file, I see the data arriving, and then

Thu Sep 08 13:10:54 2022 WARN 32320 AlcAHLLinkLayer::extractMessage : 34 unexpected bytes received, ignored

I've tried with messagesent = (STX)@FFFF(ETX) , but get a simial error ( Less unexcepted bytes ) .


Can anyone expand on what the error means ? do I need to send something prior ? What am I doing wrong ?

Any help is grateful

Thank you

Hi,
The problem is that what you are sending the initial string in text "0x02 0x40 0x46 0x46 0x46 0x46 0x03" and not the hex values of stx, @, ...
You can try changing your code to:
....
byte[] messageSent = { 0x02, '@', 'F', 'F', 'F', 'F', 0x03 };
....

BRegards
