Welcome!s,
Questions:
1. Should the proposed topology, with Kamailio + an RTP proxy
behind a firewall, relaying to FS on an inside interface, work?
(Can't see why not)
Yes, you said that your upstream is on the same private network. So it
should be pretty straight forward.
2. Does it need a local RTP proxy on the Kamailio
box, particularly
if we turn off the ASA SIP inspect stuff?
If you are all on the same private network, I would let FreeSWITCH
handle the RTP, but you can do this a variety of ways.
3. Can you recommend which RTP proxy to use? There
seem to be at
least 3 that work with Kamailio. The box is CentOS 6.5, and it would
be nice to use known-to-work packages rather than compile from source.
(But eh, if I haveta).
On your scenario, I'd just use FreeSWITCH for the media proxy. Again,
many different ways to go here.
4. Can anyone point me to some docs to explain what
ports need to
be open between the Kamailio box and my upstream proxy/media server?
I can be more liberal between inside and DMZ I guess.
Your upstream provider would generally tell you which rtp ports they
would want opened.
5. Is static NAT in this environment going to bite
me, or should
it be OK?
I've never had an upstream provider communicate with me on private nat.
6. Is there any better documentation that we should
be using to
make this easier, or should I just man up and try harder?
Man up. =)
Practive makes perfect.
