Chris, I just switch the customer from Asterisk to FreeSWITCH. The same DD-WRT firmware run smoothly for a long time with the Asterisk.I do not think there is no issue with DD-WRT firmware. I am thinking the Aastra phone. Because of calls Drop , I do not want to switch the router which is working fine. In your case Asterisk/ FreeeSWITCH in the same network. My case FreeSWITCH in the Data center( Public Network) , Phones behind the NAT I work from my home and I use the same DD-WRT firmware to connect same FreeSWITCH, but using Linksys SPA942 phone. Never have any problem. Victor, Thank you for the suggestion. I am going to capture and analyse. My question is Does anyone have similar experience with Aastra Phones & FreeSWITCH.

Hi Lloyd,

I'd start by looking on a hangup cause from FS CDR.

You can also do packet capture on your DD-WRT with tcpdump and libpcap. Or do packet capture on your FS machine. Then analyze packets with WireShark on your computer.

Regards, Victor

Thanks Brian, 1. Phone side port - I will give a try. 2. rport - already enabled. Thanks Lloyd On Thu, Dec 9, 2010 at 1:43 PM, Brian West <brian@freeswitch.org> wrote:

First off you need to change the phone side port.. you can not have two phones on the same port behind the same nat... secondly enable rport on the phone's config.

Get sip traces of it not working and revert your sofia profiles back to what is in git and I bet it will just work. So you can take your pick.. make your device do its job and not force the registrar to overcome your devices stupidness and you can have call density out the wazzo or you can pick to have FS overcome it for them chewing up more cpu and processing power trying to overcome your stupid device and then only have a handful of calls on a machine. Its really what it boils down to. /b On Dec 9, 2010, at 12:57 PM, Aloysius Lloyd wrote:

Brian,

In the current scenario Asterisk and Aastra phones working smoothly without any additional settings. All I need to enter username , password and sip server address.

But FreeSWITCH and Aastra phone - I need to enter username , password , sip server address , rport enable. Without rport enabled, phone never register to FreeSSWITCH.

Why FreeSWITCH and Nat behaving like this? What is difference between FreeSWITCH NAT and Asterisk NAT.

I do not want to go back Asterisk. I want to educate myself. Also want to switch more customers to FreeSWITCH.

Any help is appreciated.

Thanks Lloyd
