[Serusers] UAs' interoperability with SER

Hi,
This isn't a solution to your post. I just have a couple
of comments that I think will help with your debugging.
At addaline.com we have partnered with Xten. Xten works for us
public/public, public/nat and nat/nat. We are using Jasomi
for NAT traversal. The only 'trick' is to get the 'Send internal
IP' checked.
I have (over the last year) debugged quite a few problems,
usually with my understanding or configuration.
I have found that sipscenario is much better to examine
packets than ngrep. Looking at the ngrep output isn't much
better than tcpdump...the sipscenario uses ethereal (or tcpdump)
and creates a real nice call flow chart (for example:
http://www.august.net/oneway1_index.html
I don't know where this software is these days, you
can contact ray.elliott at ipc.com if you are interested
in a copy.
