Summary:                    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.

In reply to tzafrir's note.

If the channel is configured to "ls" the problem goes away but the channel
stays on indefinitely after an incoming call is hung up by a caller.

Device used:
Generic Wildcard TDM400p REV I
lspci identifies it as a "Communication controller: Tiger Jet Network Inc.
Tiger3XX Modem/ISDN interface"
