FreeSWITCH is on public IP and Phones Behind the NAT. I see sometimes FreeSWITCH send the reply to a wrong port or not responses for the registration request.

I solve the problem using the <param name="sip-force-contact" value=" NDLB-connectile-dysfunction"/> in the user directory.

But why this is happening to Aastra Phones only? Please let me know.
Thanks
Lloyd

Get the SIP trace of the phone doing its registration. Also, is the phone on the same LAN as FreeSWITCH? Is there any NAT involved?

I did some traces and figure it out the problem losing the Registrations.

1. FreeSWITCH Send the response to a wrong port . Is this a Bug?

2. Why FreeSWITCH + Aastra Registration contact not have the port number ?

3. See the below ... 

203 & 202 Aastra Phones on Domain - aastra.mydomain.com

But user Agent Shows Polycom. BTW in the same LAN I have two polycom phones on different domain foo.mydomain.com

1. FreeSWITCH Registration shows two entires in the internal profile and when I try to call to the extension two lines on the phones rings .... no idea why this is happen?

2. After first registration expires .... FreeSWITCH internal registration status shows the following entry. When I dial the extension now there is a long delay ... FreeSWITCH dialing and waiting then goes to voicemail.

3. Phones Goes randomly "No Service" .... I see this problem several times in the past.

-------------

At the same time in my lab Linksys and Polycom Phones working without any issues with the default settings.

-------------

my question what is Aastra Doing differently?

Thanks
Lloyd
