[Asterisk-Users] sip.conf asterisk to vonage

[m. smadi]

i have tried to connect my asterisk server to vonage like this:

Sip.conf:

register => 1<yournumber>:<secret>@atlas-east.vonage.net:5060

[vonage]
type=friend
username=1<yournumber>
secret=<secret>
host=atlas-east.vonage.net
port=5060
allow=all
maxexpirey=15
dtmfmode=inband
fromuser=1<yournumber>
fromdomain=atlas-east.vonage.net
canreinvite=no
nat=yes
context=default

Extensions.conf:
[default]
exten => _1<yournumber>,1,Dial(SIP/111)

and i tried port 5061 also instead of 5060 with no luck.  When i look at 
the log messages from the CLI i get the message
han_sip.c:3986 sip_reg_timeout: Registration for 
'1<yournumber>@atlas8.atlas.vonage.net' timed out, trying again

Any clues?
