Cant dial to *9901

If you get something like this:

[Mar 23 10:11:50] NOTICE[15897]: chan_sip.c:13885 handle_request_invite: Call from '456' to extension '*9901' rejected because extension not found.

Then:

• Copy Asterisk config files from /usr/src/mor/asterisk-conf to /etc/asterisk, reload Asterisk
• In device settings check Works not logged: YES
• Make sure you are not dialing from Fax device
