Sorry John.
I see it now.
I don't know how I missed that before.
My apologies.

Query is the 3rd command.

You can set the delay up to 30 seconds before it will go to diversion
(forward, voice mail, etc).

You would probably want to do **61**30# SEND  to change to 30 seconds.

*#61# will show you the current voice mail number (where your calls go
if you don't answer). This varies, and you should not it before
messing around too much with the settings.

Also remember to enter your number as 1xxxyyyzzzz  which is the
"international" represenation of a North American number, or if you
enter a number in the gsm codes.

***FINALLY***
The problem was in finding the correct voicemail #.
None of the suggestions here as to how to find your true voicemail number
worked for me.
Perhaps because this is a brand new Razr V3 ordered online from Cingular?
DUNNO.
Trying all of the different supposed voicemail numbers did extend the time
but left my callers unable to leave me a message.
It wasn't until I found the *correct* query to find my true voicemail
number.
(***John Navas, your query string "*#61*11#[SEND]" did not work for me.)***
Upon visiting the Howard forums I did find a post from someone having the
same problem as I.
He suggested trying the following query which did give me yet another
completely different voicemail number from the ones I had thought were my
correct number but didn't work and left my phone unable for callers to leave
a message.
The query that worked for me is:
*#62#
When I now used that voicemail number for the destination number and set the
ring duration to what I wanted, it now worked fine!  FINALLY!
For those trying to set longer ring times, it is crucial to enter the
correct voicemail number or your phone will not work properly.
I hope this this helps someone else and avoids the problems and hair pulling
I have just encountered.

ok this is still not working for me.
I can't do a query.
I get a message saying "Unknown Application"
So I went to the cingular site and looked up my minute useage and it listed
a number that said it was my voicemail number so I used that in the string
as my destination number but what is happening now is that the ring duration
does set to 30 as I had entered, but when i (or anyone else) calls my number
it doesn't let them leave a message.  It just assumes it's me calling and
askes me if i want to check my messages.  I think I saw something like
"forwarded sent" after I entered the string and hit send.
I am assuming here that I still must be entering the wrong "destionation"
(voicemail) number.
Any adivce?
TIA
