[asterisk-users] SIP Extensions and loss of Internet connection

Asterisk is not behind the router. The problem I'm having is in the LAN.

As I told Phil, I am experiencing the same problem both from a softphone
on a workstation with fixed IP as a Grandstream phone (which gets
network configuration via DHCP). In both extensions, the Asterisk server
is configured with IP, so in that sense, I don't think the server is
inaccessible to customers.

On the other hand, I made sure to have commented in the sip.conf file
any reference to providers such as Ekiga or iptel, so the server
should not be trying to get to the Internet.

It would appear that the server for some reason was 'locked'. For
example, when I try to register from Twinkle softphone, I get the
following:

Thanks for your reply.
