Im using realtime and setting the caller id in the db i.e. I have an entry like "Test \
User 6" <50006> in the caller ID column. This explanation may clarify a bit more:

1) Test User 1 (50001) dials 50006
2) Asterisk (Server resides in the voice DMZ with an IP of 172.16.52.80 listening on \
port 5080) sends and invite to the kamailio box's voice DMZ ip (172.16.52.70:5060) 3) \
This invite contains a From and Contact header looking like:  From: "Test User 1" \
<50001@172.16.52.80:5080> & Contact: <sip:50001@172.16.52.80:5080> 4) Kamailio sends \
the invite onto the registered client 5) The registered client displays "Test User 1 \
50001@172.16.52.80:5080"

What I would like to be displayed when the registered client rings is something like \
"Test User 1 50001@sip.domain.tld" or "Test User 1 50001@publicip" or even just "Test \
User 1 50001"

If I enable SIP inspection on the ASA that sits infront of the kamailio box, I will \
get a public IP of the gateway displayed but not the one that points to the DMZ \
interface of the kamailio box, and it still displays the internal port that the \
asterisk box is on, i.e. "Test User 1 50001@123.321.123.321:5080"

Im getting the feeling that I am not grasping something really basic, or that I have \
misconfigured asterisk somewhere along the line, as far as I can tell kamailio is \
working exactly as advertised, and the problem is originating upstream, or should I \
use kamailio to normalise the traffic emitting from it?
