SYMPTOMS
When you use the RasDial function to initiate a Remote Access Services (RAS) connection over an Integrated Services Digital Network (ISDN) adapter, a connection to only one channel may be created (instead of a connection to two or more channels).



CAUSE
Even if the phonebook entry is configured for multiple channels and works correctly when you invoke it manually, RasDial establishes only a single-channel connection with some ISDN adapters.



RESOLUTION
Use the Rasphone.exe command-line tool to call the Dial-Up Networking phonebook. For additional information about using Rasphone.exe, click the article number below to view the article in the Microsoft Knowledge Base:
