Things to check:

1. In sip.conf should be such line:

[general]
#exec /usr/local/mor/mor_ast_register SIP

2. In asterisk.conf:

execincludes = yes (not commented out!)

3. Correct DB connection settings should be present in:

/var/lib/asterisk/agi-bin/mor.conf

4. If you have some registration info entered in your GUI, then executing such commands:

cd /usr/local/mor
./mor_ast_register SIP

Should show your register line(s).

5. When you click on Save device settings (update) you should see some action is Asterisk CLI.

If you don't - make sure you have correctly configured SETTINGS - Asterisk Servers window.
