[Freeswitch-users] Polycom IP 335 - 401 Unauthorized .... NAT ISSUE?

[Sean Devoy]

HI All,

 

I am still banging my head against the wall here try to get a Polycom 335 to
register w/ FS.  I have checked all the SERVER and USER/AUTH fields like
1000 times and 900 variations.  I think my problem may be NAT related.  I
know on my CISCO 504G I had to enable several NAT features to work behind
our firewall.  I am totally new to Polycom, so some very basic help is
needed.

 

The server is remote but not behind a NAT there.  The phones are NAT'ed to
the internet.  In the sofia sip trace I see this over and over:

If I understand correctly, the server should be sending back this 401
message with the nonce so the phone can re-attempt the registration with an
encrypted password.  If NAT is failing, the phone is never seeing the 401 w/
the nonce.

 

So what do I do in the WEB config interface to enable NAT on this phone?

 

Thanks,

Sean
