asterisk users - Sep 2004 - Dialing Out through Provider with Authentication

Hi,

I try to dial out through a Provider, but for that i need to be
authenticated - it actually does not work !.
What kind of dial command do i have to use when i:
- Want to authenticate the user 
- And dial with that authenticated user an extension
 
What i tried so far 
exten => _7.,2,Dial(SIP/USERNAME:PASSWORD@PROVIDER.COM/${EXTEN:1})

what have i done wrong ?
i always get back a Service Unavailable !

For my tests I did not need to be authenticated.  This is what I used in
asterisk:

exten => _7.,2,Dial(SIP/PROVIDER.COM/${EXTEN:1})

When I tried to use your scenario, as below

exten => _7.,2,Dial(SIP/USERNAME:PASSWORD@PROVIDER.COM/${EXTEN:1})

Here's what I get in my logs:

Sep  9 18:10:56 WARNING[137570304]: chan_sip.c:902 create_addr: No such
host: PROVIDER.COM/72312

What I gather from this is that its not legal to Dial() like that.  In my
limited SIP knowledge, it makes sense - you do not need to have a username
and / or password to place calls to extensions that a given provider (e.g
PROVIDER.COM) serves - if they do not serve those extensions, they will
give a "404 Not Found" error.

Hope that helps...

Hi,

I tried to make a call to extension 2001 with the setting
2000@provider.com (Detailed:
exten => _7.,2,Dial(SIP/2000@provider.com/${EXTEN:1}) 
which does not work at all - i always get the failure message: No such
host provider.com/2001 (the number i dialed) - why ??
when i try the same with a peer agent (exten =>
_7.,2,Dial(SIP/provider_out/${EXTEN:1}) - i always get the failure
message 
WARNING[-178521168]: chan_sip.c:680 retrans_pkt: Maximum retries
exceeded on call 0ac244f146d85c325ca3357b4db1d05a@192.168.0.7 for seqno
102 (Critical Request)

What am i missing ??
I am running out if ideas !.

What I understood from Karl's message is that you need to create a peer in
sip.conf.  For example below:

-- sip.conf --
[myprovider]
type=peer
username=USERNAME
host=PROVIDER.COM
secret=SECRET
--

Then in extensions.conf, do the following:

--
exten => _7.,2,Dial(SIP/myprovider/${EXTEN:1})
--

This should work.  What Karl meant is that using the statement below:

--
exten => _7.,2,Dial(SIP/2000@provider.com)
--

Will only work if you are dialilng a *specific* extension on provider.com.
The statement below:

--
exten => _7.,2,Dial(SIP/2000@provider.com/${EXTEN:1})
--

Is illegal.


Cheers,
