Hi,
As the title says this is what I have problems with. However, I can register Zoiper both over TCP/UDP.

<EDIT>
I've read the post underneath suggesting register phones with TCP which I also have tried to no avail

Setup: AWS
I currently have a freeswitch up and running on AWS which works. I can register the same phone to freeswitch but not to fusionpbx.

On FusionPBX I have everything else working except registering the SNOM phones. I've setup provisioning of a SNOM phone which also works.
Tried with one identity to register with fusionpbx and the other to register with freeswitch, The one to freeswitch registers.
If I use the same extension ID/Passwd on zoiper it registers.


I've whitelisted all necessary IPs in
/etc/fail2ban/jail.local separated by space
[DEFAULT]
ignoreip =

I don't get a reply to the registration message.

What I can deduce from these messages are that the authorization is not coming through.
Attached is the output from: iptables -L -n

Any ideas how to go about this?

I'm marking this as solved.

It was a typo on my end.

On the snom phone;
Identity
Outbound Proxy
<IP_of_PBX; transport=tcp

I've put a comma instead of a semicolon

Stil I wonder why I could register zoiper over UDP and I can register over UDP on the freeswitch server.
