> Hi,

>   I have setup and configured asterisk server using SIP. I defined

> [2000]
> type=friend
> username=2000
> secret=hi
> host=dynamic
> context=from-sip
> mailbox=100
>
> [2001]
> type=friend
> username=2001
> secret=hi
> host=dynamic
> context=from-sip
> mailbox=101
>
> I made entries in extensions.conf, shown below, to place calls to
> 2000 and 2001

> [from-sip]
> exten=>2000,1,Dial(SIP/2000,20)
> exten=>2000,2,Voicemail(u2000)
> exten=>2000,102,Voicemail(b2000)
> exten=>2000,103,Hangup

>  Initially I tested out the server by registering SJPhone user

>
> To: <sip:2000 at 192.168.0.44:5060>

> and this is what it looks like when it is forwarded to the callee by
> asterisk (192.168.0.243 is the IP address of the callee).
>
> To: <sip:192.168.0.243>
>
> Since the URI does not contain the user part the callee replies with
> 404 not found and the call fails. I have thought hard, compared
> signaling traces but cant really make out how to make my gateways
> work, seems like an asterisk bug. Any ideas? I would really appreciate any
> help in this regard.
