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

<div>Hi there,<br>
<br>
I have two FS servers (FS1 and FS2) behind an inbound OpenSIPS proxy.
Outbound (terminating) traffic goes directly from each FS box.<br>
<br>
All my home office phones get calls no matter which box they are
registered with or which box the call comes in on - thanks Anthony.<br>
<br>
However my SIP client on various iPhone/Androids etc only receive calls
that originate on the box on which they are registered.<br>
<br>
Looking at the SIP trace - when the call comes in on the 'wrong' box,
the invites to these SIP clients do not even get a response. Presumably
because the 3G network has no idea who this new IP in the "from
address" is, who trying to contact them.<br>
<br>
Question is, is there a way around this - our will I have start routing
all terminating traffic out through the proxy also.<br>
<br>
Any insight appreciated.<br>
<br>
Thanks!<br>
