[Freeswitch-users] Natting question.

[Sean Devoy]

Hi Mimiko,

I have had hours and hours of problems with NAT, so I can at least tell you
what helped me get past them.

All of my problems have been in the configuration     PHONE > NAT > Internet
> FS  .

CISCO SPECIFIC ISSUES:
I learned through a long tough week with a new customer that CISCO 3xx and
5xx Series have a web setup section that is critical when behind NAT.  When
logged in as an ADMIN, on the SIP Tab, these NAT Support Parameters should
be set to yes:
Handle VIA received,  Insert VIA received,  Substitute VIA Addr,  Handle VIA
rport, Insert VIA rport, Send Resp To Src Port
With those all set I have had pretty good luck with CISCO.

GENERIC TO ALL PHONES:
Brian and Michael have just worked me through a similar Registration issue
with Polycom phones, but I am sure this applies to many others too.  The key
to understanding that it was a NAT issue was that the phones CSeq (in the
Sophia global sipstrace on) did not change from one attempt to the next.  It
was always "CSeq: 1 REGISTER" and the second one would be "2 REGISTER" with
the auth stuff attached.  That shows it did not receive the response.  In
this case I added a parameter and a variable to the USER section of the
"directory" on the server.
          <variable name="sip-force-contact"
value="NDLB-connectile-dysfunction"/>
         <param name="NDLB-force-rport" value="true"/>

I am not sure if that fits your case, but maybe it will help others in the
future.

Sean

Hello.

I have a FS behind firewall on which ports 5080,5060 udp are mapped to the
FS server. A client connected directly to Internet, say using GPRS,
authorise to FS and calling a number audio is heared. When this client is
connected via WiFi to some router connected directly to Internet, client
authorises, calls but there is no audio.

So I'm stump on where to look for issue: on FS server side with firewall or
on client side behind router?

Thank you.
