wvdial works -- ifup fails

[Phil Meyer]

Here is wvdial.conf:

[Modem0]
Modem = /dev/ttyUSB0
Baud = 460800
SetVolume = 0
Dial Command = ATDT
Init1 = ATZ
Init3 = ATM0
FlowControl = CRTSCTS
Stupid Mode = 1
New PPPD = yes
[Dialer cingular]
Username = isp at cingulargprs.com
Password = CINGULAR1
Phone = *99***1#
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Inherits = Modem0
[Dialer sprint]
Username = moo
Password = foo
Phone = #777
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Inherits = Modem0

Nothing fancy as you can see.

Here is /etc/sysconfig/network-scripts/ifcfg-cingular

# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
ONBOOT=no
USERCTL=yes
PEERDNS=yes
TYPE=Modem
DEVICE=ppp0
BOOTPROTO=dialup
AC=off
BSDCOMP=off
VJCCOMP=off
CCP=off
PC=off
VJ=off
LINESPEED=460800
MODEMPORT=/dev/ttyUSB0
PROVIDER=cingular
DEFROUTE=yes
PERSIST=yes
WVDIALSECT=cingular
MODEMNAME=Modem0
DEMAND=no
IPV6INIT=no
IDLETIMEOUT=600
DEBUG=yes


again, nothing fancy.

The problem:

wvdial works like a champ:

What am I missing?  It is driving me crazy!
To make matters worse, this works in another system that is
configured the same. :(
