No device error on AX Client Startup:

Today I came across a weird issue while opening AX2009; it was never an issue before.


This error message is caused by the ActiveX component for the phone integration on form smmPhone which returns an error for each phone device which is offline.

In order to prevent the error message, just edit the code in smmForm, here is the path

What is TAPI??

TAPI (Telephony Application Programming Interface) is a Microsoft Windows standard interface for integration between telephone systems and windows based software. A typical example is integrating called ID with a database on your computer that contains detailed information about potential callers. When your phone rings, a window pops up
on your computer with information about the caller. This is possible through software applications that are TAPI compliant and support the Screen Pop and Auto-Dialer capabilities.

You can do the following code changes to prevent the error message:

// AOSRunMode::Client
void onEvent_TapiError(int errorCode)
if (errorcode != -2147483582)
