[Serusers] SER + mediaproxy or STUN

[Iqbal Gandham]

Hi

I have installed ser with STUN support, since my routers are not 
symmetric, in theory this should solve natting issues, however I seem to 
get completely random results. I am using xlite softphones behind the 
SAME nat to make a call, they can call out to pstn (via asterisk), 
however one phone can call the other across the internal network, but 
not vice versa, even though both PC's are on the same network. The 
ser/asterisk/stun boxes are on apublic network.

I came across a post which using a tcpdump would draw a diagram of the 
sip call path, does anyone have the url/name for that, I just cant see 
what wrong in the sip debug messages, maybe a pic will help me out.

tks

Iqbal
