[Freeswitch-users] AASTRA Phones - NAT issue

Fri Oct 17 08:55:48 MSD 2014

Brian,
Thanks for the prompt response.  However, I have searched the web config pages, users guide and administrator’s guides.  I cannot find any reference to “rport”.  Could it be hiding under some other name I don’t know?

Here is the SIP config page:

None of those will have anything to do with this issue, in fact most of those aren't even needed, enable rport in your device and the problems go away.  None of those can actually apply during the challenge phase its a chicken egg scenario as the user isn't looked up at that point, its just a blind challenge.

i have a deployment with 10x480i's 20x6730i's and 8x6757i's

i use <variable name="sip-force-contact" value="NDLB-connectile-dysfunction"/>

and i have aggressive-nat-detection enabled, as well as some other NDLB settings in my internal.xml
Brian mentioned rport, i don't personally use it with any of my stuff, however i have seen it used in the past.
Here's the settings i have set, not sure if all of them are needed, but i do have working 480i's with this configuration

<param name="aggressive-nat-detection" value="true"/>
<param name="NDLB-broken-auth-hash" value="true"/>
<param name="NDLB-sendrecv-in-session" value="true"/>
<param name="NDLB-received-in-nat-reg-contact" value="true"/>

And by rport I mean in the Aasstra phone.

Its because you don't have rport enabled, if you notice your register says in the contact 71.121.183.4:5067<http://71.121.183.4:5067> so thats where we send the 401, chances are your phone doesn't get it because we are going to the contact.  In this case the phone never gets the 401 and we keep sending it.

Hi All,

I am trying to get an AASTRA 480i working with FS.  I have other phones working just fine (Cisco and Polycom).  I have updated the firmware.  I can see in the “sofia global siptrace” the REGISTER request, the Unauthorized response, but it does not appear to be making it back to the phone.  That statement is based on my observation the CSEQ does not change.

I have added and removed:
  <variable name="sip-force-contact" value="NDLB-connectile-dysfunction"/>

I have tried many different option through the phones web interface, but no luck yet.

Anyone have a working configuration (phone and FS) they could share)?

The key siptrace packets are here (these happen to be from the attempt with both UDP and TCP):
