[SR-Users] SL local ACK found -> dropping it! error ...

[Klaus Darilion]

With this trace I do not see a problem regarding your previous post "SL 
local ACK found -> dropping it!  error"

But for sure you have a problem as the incoming INVITE is malformed. 
Either Bria iPhone is buggy or there is a FW/ALG device which rewrites 
the SIP packet (IP addresses) and does it in a wrong way (same old story 
with ALG).

To verify if the problem is due to an buggy ALG you could try to start 
the SIP proxy on a different port, .e.g 45671 - whatever you like - anc 
configure Bria to use this port.
