Setting number of rings before answer on RAS

[Marcos Aurelio]

Greetings,

We´re having problems setting number of rings before answer on RAS.

We´re using NT Server 4.0 SP3 and we´ve tried to configure the modem.inf file as
described in Article ID: Q114687, but the modem continues to answer on first ring.

Can you help us?

Thanks in advance.

That article says it only applies to 3.5X
The other article is this one....Article ID: Q145879


The information in this article applies to:
Microsoft Windows NT Server version 4.0
Microsoft Windows NT Workstation version 4.0


SYMPTOMS
By default, the Remote Access Service (RAS) from Windows NT, answers incoming calls after the first ring. The documentation in the Remote Access Administrators Help file describes how you can modify the RAS Modem.inf file to change this behavior. However, this only works if RAS is not using any Telephony Application Programming Interface (TAPI)/Unimodem-based devices.



CAUSE
Beginning in Windows NT 4.0, RAS is capable of using TAPI. It also maintains backwards compatibility with Windows NT 3.51. However, RAS is not capable of using both TAPI and the Windows NT 3.51 Modem.inf information. If RAS is using TAPI, then modifying the Modem.inf file to change the number of rings to wait before answering has no effect.



RESOLUTION
In Windows NT 4.0, to set the number of ring messages from the modem after which RAS will answer the call, add the following key to the Registry:


HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services RasMan Parameters

Then add the following REG_DWORD value to this key:

NumberOfRings

This REG_DWORD registry value can be in the range of 1 to 20. If this value does not exist, or is outside of this range, the default value of one (1) is used. If RAS is not using TAPI, then this value is ignored and the documentation about modifying the Modem.inf file is correct.
WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.
