TAPI Updates for Windows CE 3.0 Core Operating System (285398)
The information in this article applies to:
- Microsoft Windows CE Platform Builder 3.0
This article was previously published under Q285398 SYMPTOMS
The following Telephony API (TAPI) issues have been addressed in the update that is described in this article.
- An exception can occur when a TAPI-aware program allows a blind call transfer to an unspecified number.
The TAPI lineBlindTransfer() function does not check the lpszDestAddress parameter for NULL before calling the TAPI Service Provider Interface (TSPI) function TSPI_lineBlindTransfer(). A NULL destination address will eventually cause an exception when TAPI attempts to message call clients about the call state change. - Under system stress conditions, the internal TAPI call list can become corrupted, causing a Device.exe exception. This problem can occur while making a call.
- Under test (or system stress) conditions, Connection Manager may cause an exception while attempting to put a conferenced call on hold.
- If you make a conference call and send '21SEND' from the call progress view, TAPI removes the first call from the conference, but does not clean up the conference list. Therefore, it still appears to to be in the conference to TAPI programs. Additionally, it may not be possible to put the affected call on hold, or remove it from hold. Note that the TAPI lineRemoveFromConference() function works properly. When you click Private on the menu during a conference call, the feature is handled by TSPI_lineRemoveFromConference. However, when the in-call command "21" is run, it is handled by TSPI_lineDevSpecific.
- An exception can occur when a TAPI-aware program allows an attempt to make a call to an unspecified number. This can occur when the lineMakeCall() function is called with a NULL lpszDestAddress parameter.
- RAS connectivity may not work on systems with relatively slow processors, or multiple TAPI devices.
While AsyncMac is initializing, it negotiates an API version (by using the TAPI lineNegotiateAPIVersion() function) with the TAPI Service Provider. If TAPI has not completed initialization, the call may not succeed, rendering AsyncMac unable to communicate properly with TAPI, which causes RAS connectivity not to work.
This is sample output from Eshell when an unsuccessful attempt to establish a RAS connection occurs:
CSPRAS : i : Connect: Asked to connect conn 0x61f30
CSPRAS : i : Connect: Beginning to connect...
CSPRAS : i : Connect: RasDial failed, m_hRasConnection=0x0
CSPRAS : i : DisconnectDone called on conn 0x61f30, new status=0x20
