I'm having trouble getting a voice call to originate after I've made several data calls using IWeb. ITAPI_MakeVoiceCall() is returning EALREADY, and the TAPIStatus is 'conversation' and the 'data' flag is set (although there are not any current or pending data calls). I assume this behavior is being caused by the PPP link still being active.

Is there any way to force the PPP link to close, so I can make an outgoing call? I've read this thread

But it suggests using INETMGR_SetLinger() to set the linger time of the PPP link to 0, which a lot of carriers really frown on. Is there any other way?
