The extensions have configured the Asterisk server by its IP, so I do
not think there is a problem on that side.

To enable debug I should use 'sip set debug'? from the Asterisk CLI? I
do not see any record in the CLI after running this command. However,
from Twinkle, for example, I see the following:
