[asterisk-users] Can't connect to voip provider over NAT

[Landy Landy]

According to my provider they´re not receiving any request from us but, now everytime I try to place a call through them I´m getting:

*CLI> sip show peers

  == Using SIP RTP CoS mark 5
    -- Executing [18008909999 at default:1] Dial("SIP/102-b6a05db0", "SIP/18292574075 at voipprovider") in new stack
  == Using SIP RTP CoS mark 5
    -- Called 18008909999 at voipprovider

It just hangs here and nothing happens..........


Here´s my sip.conf file:

[general]
externhost=myexternalip
localnet=172.16.0.0/16

register => username:password at sip-gw.advancedvoip.com.do

allow=all

[voipprovider]
type=peer
host=sip-gw.advancedvoip.com.do
username=username
fromuser=username
secret=password
port=5060
canreinvite=YES
dtmfmode=rfc2833
nat=yes



What I´m I doing wrong?
