Summary:                    SIP over TCP and TLS does not appear to support
NAT=yes
Description: 
I am using a soft client to test SIP over TCP and I am having problems
getting RTP to send traffic back to my NATed ip address. Nat works
perfectly with UDP but not with TCP or TCP/TLS.

Here is the output from my RTP Debug

TCP connection gives me this
Sent RTP packet to      192.168.49.16:10004 (type 09, seq 043932, ts
108160, len 000170)

Which never gets back to me because its my private IP.

UDP connection gives me this
Sent RTP packet to      99.137.230.28:10000 (type 09, seq 015177, ts
000320, len 000170)

Works great.

I found my problem,
I needed to open the RTP ports on the router in front of asterisk. Looks
like the ALG was doing this for me on UDP but it cannot see into the
SIP/TLS packets to do it. When I manually opened these ports my problem
went away. Thanks for pointing me in the right direction with RTP.
