Summary:                    [patch]Asterisk can't establish dialtone after brief
hangup
Description: 
Asterisk can't establish dialtone after brief hangup

When I press the hook-switch (i.e., receiver button) and then let go to
make a new call, the phone doesn't establish dialtone unless I hold it down
for for 4-5 seconds.

Reproducible Steps:
1. Pick up handset and establish dialtone.
2. Press the hook-switch for 1-3 seconds and let go

After letting go of the hookswitch, the sound on the line is silent for a
moment then a computerized squeal is heard briefly and silence continues.
The asterisk console displays the following messages when "core set verbose
10":
--------------------
    -- Starting simple switch on 'Zap/7-1'
    -- Hungup 'Zap/7-1'
[May  3 11:31:45] WARNING[2241]: chan_zap.c:1616 zt_set_hook: zt hook
failed: Device or resource busy
--------------------

We are using analog Astra Telecom 480e phones connected through internal
wiring to TDM400P cards in our asterisk server.

Undoing the change in revision 3883 until there can be more thought about
the 
best place to configure the battery debounce time.  Too short and
erroneous

side disconnects.
