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,

Thank you for clarifications. I bet [^] has something to do with
hyper-links.

You may want to change "cd dahdi-linux" to "cd dahdi-linux/2.1.0.4" in
your instructions otherwise 'patch' command has trouble accessing
sub-directories.

Now regarding the 'reversepolarity' issue. As I understand, it is a known
issue and polarity in TDM400p FXS lines is normally reversed unless the
'reversepolarity=1' parameter is passed to wctdm at startup. Is my
understanding correct? This is what I observe with my hardware.

I also confirm that the first call is needed after reboot to reset the
polarity back to normal. Return to normal only occurs if
'reversepolarity=1' parameter is passed to wctdm at startup, otherwise the
polarity stays reverted all the time.

Should I keep the 'boostringer=1'?

Thank you,
Vladimir
