Summary:                    [patch] Call to a FXS DAHDI channel with Panasonic
KX-TG4000 connected drops in 8 seconds randomly
Description: 
More often than not a call placed to a DAHDI channel with Panasonic
KX-TG4000 connected would drop on its own in exactly 8 seconds after being
answered. Before being disconnected two (2) clicks are being heard in
succession. The second click kills the connection.

Alec,

Maybe my question is completely irrelevant, but let me ask.

Do you think that the wctdm patch, second edition, i.e. diff2, could
introduce a problem with DTMF when a call comes in on a SIP trunk?

This is what I see. A call comes in from PSTN via SIP Broker, terminates
on my AsteriskNOW via Gizmo5 SIP trunk, caller dials a Panasonic KX-TG4000
extension (so far so good, DTMF works fine that far), call gets connected
to the Panasonic (patch works fine, the line does not drop in 8 seconds),
caller tries to dial a Panasonic extension with no luck, DTMFs are not
recognized at all.

Thank you,
Vladimir
