We have an S300 PBX setup on a /23 network.
PBX on 192.168.90.2/23 subnet of 255.255.254.0 and a GW of 192.168.90.1.
Now we have run out of the first /24 of the /23 IP's which are used on phones. So I started using 192.168.91.2 on a phone. It does not register at all.
[2017-07-13 19:21:55] WARNING res_pjsip_registrar.c: register failed ! endpoint open remote register restrict
To get it to work in the extension setup I had to tick "register remotely"???
This makes no sense? Why would that need to be ticket, everything is on the same subnet.
