16.7 Legacy Series / Cannot register more than one VoIP phone
« on: December 14, 2016, 09:58:01 pm »
I am doing some testing on a freeSwitch based PBX that I have setup with a public IP on a separate ISP. I have 4 phones that I'm attempting to test with from my office - 2 snom and 2 fanvil phones. Whichever phone of each model registers first registers fine and works great. The second phone to attempt to register does not ever receive a response from the PBX.
This issue was happening on 16.1, so I upgraded to 16.7 and it's still happening.
Static ports are enabled in outbound NAT. None of the phones would register at all without static ports.
Enabling and disabling reflection doesn't seem to make any difference.
Firewall optimization is set to conservative.
Any other ideas of what to try?
