Hi Jeff, Thanks for the insight. Forgive my ignorance but if I have two Identical Freeswitch servers with SRV records and endpoints that properly support SRVs, why do I loose the ability to failover if one host is not reachable? Also as many of these end points are Polycoms behind NAT, I can't see any reason I'd still need NDLB-force-rport on the profile? Since these are application servers, handling conferences, presence, etc., I'd imagine I would hit other bottlenecks before I hit the TCP connection limit.

That I would agree with, but the thing is you lose the capability of failover in the unlikely event that a node in a FreeSWITCH cluster fail.
In my opinion, TCP seems better than UDP as you know all the SIP packets are making to their destination.

On a Linux system there is a limit of how many open TCP connections you have.
If I can remember correctly, I think Darren from 2600hz did discuss about the limit of open TCP connections you can have on a Linux system. Correct me if I'm wrong on this, but that seems to be the case. And I have seen instances of that happening on a misconfigured Squid Proxy
I never heard this before...where and how it this limit defined?
Unless you have a crazy amount of endpoints you have to serve, TCP probably isn't really worth it in my opinion.
Assuming it's one Open TCP connection per endpoint, you'd probably need more endpoints than the maximum amount of open TCP connections to hit that problem
How many endpoints?
Also did I also mention that TCP connections don't really fix NAT issues?
