[Freeswitch-users] mobile phone clients / fs cluster

[Tod Hansmann]

Phil (Or do you prefer Phillip?),

You will need to probably draw this out a bit.  What is the path by 
which the home office phones connect to the FS boxes?  What path do the 
cell phones take?  What routes do you have for the return data on each 
box?  Are any NATs/Firewalls involved?

I think this is firmly a networking question.  The proxy might come into 
play as well here.  The 3G networks are just like connecting wirelessly 
to the internet.  Depending on your provider, your phone gets an 
internet addressable address, or just an internal network address which 
is NATed before going to the internet.  That NAT can be tested, if you 
have the right tools on your phone and what you're connecting to, but 
that will change from provider to provider and maybe even day to day, 
location to location.

That should be enough to start thinking about the problem and where it 
might lay.

Cheers,

Tod Hansmann
