I am desperately searching the net for “TELEPHONE.INI” to no avail.

What I would like to know is the purpose of each parameter in it, and whether there is a need to tweak it in order to improve the performance.

Can somebody help please…

What's this for?

Maybe this will help.

To the question of LLXX, the telephone.ini file (resides in %windir%) is the actual Windows file where the settings for the Dial-Up connection are stored. As far as I know, it is only used a.o. in Win98SE, it is not found under WinXP. It is a very short file containing following lines:

[Providers]

NumProviders=2

NextProviderID=3

ProviderID0=1

ProviderFilename0=UNIMDM.TSP

ProviderID1=2

ProviderFilename1=WAN.TSP

[Provider1]

NumLines=1

NumPhones=0

[HandoffPriorities]

RequestMakeCall=DIALER.EXE

A little more info here.

I see... I didn't know this since I don't use directly connected dial-up modem.

I appreciate charles’s help. Those MSKB articles certainly shed more light on the subject.

However, I would be grateful if someone could help me to get information on what each line is doing in that TELEPHONE.INI.

For example, in my Win98SE PC, I once had following line (I don’t know what program has done it):

NumLines=33

After running Tapiini.exe it becomes as follows:

NumLines=1

But according to MSKB 120221, that value NumLines=1 is meant for WinME, for Win98 it should be NumLines=2.

Therefore I am very curious to know, e.g., what that line NumLines= is for, certainly also on the other lines in the TELEPHONE.INI.
