Please look at the wireshark sip requests for my AAstra 480i phone and my Patton M-ATA ata. See that the first attempt by Aastra to register never works. Only the second works as shown below, I am not making the AAstra phone do the second request, it just does. Also, the Patton never works and only tries to send once. I have another device that only sends once and will not register either it is listed below. It is a Cyber Data IP Intercom. Could someone see the common thread here? What is going on?
