asterisk users - Oct 2005 - redirecting incoming calls to external phone (cell)

Hi-

I am attempting to setup Asterisk for the first time, and I think I am about 
99% there.   I am using vonage softphone, and want to use asterisk to 
redirect incoming calls to my cell phone primarily, and maybe other remote 
lines.

Right now, I am able to register with vonage, and trap incoming calls.  The 
only issue I have is that I don't think my syntax in extensions.conf is 
correct to dial out to my cell:

XXXXXXXXXX --> my vonage softphone number
YYYYYYYYYY-> my cell phone number


sip.conf:
[sphone.vopr.vonage.net]
username=1XXXXXXXXXX
port=5060
nat=yes
type=friend
secret=XXXXX
host=sphone.vopr.vonage.net
fromuser=1XXXXXXXXXX
fromdomain=sphone.vopr.vonage.net
dtmfmode=rfc2833
auth=md5
canreinvite=no
context=out
;
[vonage-in]
username=1XXXXXXXXXX
type=friend
port=5060
nat=yes
secret=21V9bkQ5MR
host=sphone.vopr.vonage.net
insecure=very
fromuser=1XXXXXXXXXX
fromdomain=sphone.vopr.vonage.net
context=in
canreinvite=no
auth=md5

extensions.conf
[in]
;exten => s,1,Dial(SIP/1YYYYYYYYYY,25,rt)
;exten => s,2,Ringing()
;exten => s,3,Wait(60)
exten => _1XXXXXXXXXX,1,dial(sip/1YYYYYYYYYY,20,r)

[out]
exten => _1NXXNXXXXXX,1,Dial(SIP/1XXXXXXXXXX@sphone.vopr.vonage.net,25,rt)

Right now, when I get an incoming, this is the message I get:

From: "ZZZ-ZZZ-ZZZZ"
