[chan-capi-users] D channel signalling, while B channels busy?

[Stefan-Michael Guenther]

Hi,

I'm running a number of asterisk installations with EICON/DIALOGIC and
AVM cards, together with different versions of chan_capi.

All installtions share a strange phenomenon:

Although all B channels are busy, another incoming call to a free phone
lets this phone ring. When I pickup up the phone, the caller suddenly
hears the busy tone and I hear nothing.

Could it be, that the D channel is forwarding a call, although it could
never be accepted? Is there a way to change this behaviour because to me
it doesn't make sense and it is rather annoying experience for the caller.

Thanks for your help,

Stefan
