[SR-Users] SIP Trunks Location

[Jose Suero]

Hi

I'm planning to set kamailio in front of an farm of pbx servers 
(haven't decided on freeswitch or asterisk) there's a million tutorials 
on how to do this, what I haven't found is what part of my setup 
actually handles the sip trunks my phone company provides me with.

What's the best practice when It comes to this?

Is kamailio going to be receiving the calls from the trunk and passing 
them to the PBX or is it the other way around?


please advice

Thanks in advance
