[SR-Users] basic Kamailio frontend to Asterisk

[Travis Ryan]

All,


I would like to use Kamailio as a frontend/proxy for an asterisk 
machine/cluster. I'm very well versed in Asterisk, but VERY noob to 
Kamailio.

I've watched so many Kamailio presentations and feel like I've scoured 
the web for any article that could help me. There is alot out there, but 
I'm not finding my exact situation.

I believe I understand the dispatcher stuff that I'll need down the 
road, but I'm having issues understanding the setup of my SIP trunk and 
Kamailio.

I used UAC to setup the trunk connection in Kamailio and it sort of 
worked. I'm not sure what I do for Asterisk. I'd suspect that in this 
situation Kamailio would handle the registration and trunk connection 
for me.

What role is Kamailio to my Asterisk? Just an Outbound proxy? Do I need 
to still register the trunk from each Asterisk box "thru" the Kamailio 
proxy, etc?

Also, I'm merely accepting outside calls and then validating the caller 
and bridging them back out to the PSTN, so I don't have any local SIP 
clients, etc., so no need to register the sip devices, etc.


Thanks!

Travis
