TITLE   :PhoneSelectExtVersion Is Not Called When phoneOpen Is Called
PRODUCT :Microsoft Windows NT
PROD/VER:winnt:4.0
OPER/SYS:
KEYWORDS:

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT Server version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When developing a TAPI 2.1 compliant application and when the application does
an open line from the client using the call lineGetID(), it will return an index
number based on the server (for example, 24 when only one phone is available to
client) and subsequent phoneOpen calls will fail because the client actually has
only access to one phone device as indicated by Tsec.ini.

CAUSE
=====

When tracing this from the server, and when entering an extension version in
phoneOpen, TAPI is properly calling TSPI_phoneSelectExtVersion but on the
client, TAPI does not call TSPI_phoneSelectExtVersion.

==========
