Net2phone - Asterisk

Hi there,

I am having some problems while trying to place phone calls through Asterisk to Net2phone, this is my setup:

I have a SIP phone connected directly to my Asterisk box from where I want the call to origin; in sip.conf:


I read that I have to make some changes in sip.conf, in order to make it work with Net2phone: … +Net2phone

So these are the changes I made in sip.conf:

useragent = X-Lite release 1103m
register =>

type = peer
host =
username = PHONENUMBER
secret = PASSWORD
fromuser = PHONENUMBER
fromdomain =
context = incoming
insecure = very
canreinvite = no

Now here is my extensions.conf:

exten => _9NXXNXXXXXX,1,Dial(SIP/net2phone/${EXTEN:1})

If I type “sip show registry” in the Asterisk console, it shows that the state of the Net2phone sip is “Registered”.

The problem is that when I call any phone is USA: 1-XXX-XXX-XXXX, I only get a busy tone. So I can never really place a call.

What can be the problem?

I am using Asterisk 1.4.2 on Red Hat Enterprise Linux 5.
