[SR-Users] Kamailio-Asterisk real-time integration with Dynamic IP

[Daniel-Constantin Mierla]

Hello,

forgot about this email after I saw it -- thanks for sharing, I
appreciate any contribution to documentation and tutorials. I am sure it
will be helpful for others looking at same topology for
kamailio-asterisk integration.

If you want, you can create a tutorial with your version on the wiki
from kamailio.org.

Cheers,
Daniel
