Also, unfortunately, Asterisk does NOT listen for dialtone before
dialing, so these problems will continue until someone sees fir to fix it.
As an aside, for those who pulse dial, rather than DTMF, the "w" will
not work, as it only works in DTMF

It's normal to have to wait (under a second in your case) for a dial
tone from the phone company when seizing a line.
If you were placing a call on a phone directly connected to the phone
company, the time it takes to physically pick up the phone and move
your hand to the dial normally takes at least a half a second, giving
the CO time to start the dial tone and prepare to receive the dialed
digits.
In the old days, one actually had to listen for the dial-tone before
dialing, as the phone company equipment would not necessarily be ready
to receive your digits in 1-2 seconds. With modern electronic
switches, though, a constant delay of 0.5s - 1.0s should be fine.

That did help. But can you help me understand why this is needed? I
did not
notice any of the other issues you mentioned but I do notice that it

an unusually long time to hang up the channel when it is done with
the call.
It almost seems like the signaling is not right. I was discussing
this issue
with someone offline and from what I understand, the POTS lines are on
loopstart. If that is true why do we use koolstart on the zaptel
channel?
Just as an experiment I did change the signaling to loopstart but
that did
not help either. The biggest issue is that I am in an area where just
about
all of the business are using POTS lines exclusively, and adding a
pause to
all of these just seems like a hack to me rather than fixing an
issue. I'm
not saying this is not my misunderstanding, because it may well be,
but I am
just looking for the exact answer.
Thanks

Dial(ZAP/g0/w18003569377|120)
This will put a .5 second wait before dialing to allow the telco
equipment to get ready to receive DTMF.
Have you noticed other issues like, even when calling busy numbers, you
hear a ringing tone for about 5.5 seconds before you hear a busy tone?
That's because you are using the "r" option to Dial.
