Wifi setup

Very little experience and inherited the system
Have no problem getting sip registration when the phones are plugged, all phones are on the 10.17.0.0
no problem get the phones on the wifi 10.15.0.0 then they lose the registration. Cant find sip server

I can log into the phone on the 10.17.0.0 address and the 10.15.0.0 address.
phones are the Fanvil x201 and Sangoma s705
Freepbx is 15
is there a trick to log the wifi phones onto the Sangoma Freepbx server?
office ips 192.168.1.0
phone ips 10.17.0.0 has 15phones
wifi 10.15.0.0
is there a trick to log the wifi phones onto the Sangoma Freepbx server from anywhere? aka home office

From a registration point of view, WiFi is no different from being directly plugged into a hardwired LAN.

Do you have NAT on the server, as well, and if so, did you remember to include 10.15/16, as well a 10.17/16, as local networks?

Does the machine running FreePBX access a router that knows how to reach 10.15/16? Does the phone know how to reach 192.168.1/24?

the FreePBX Sip NAT shows 10.15/24, 10.17/24 and 192.168.1/24
firewall trusts 10.15/24 10.17/24 192.168.1/24
the router/switch UMDpro connects everything

machine 10.17.0.149 running GUI FreePBX pings everything
IT machine 192.168.1.103 pings all including 10.17/24 but not Asterisk server 10.17.0.240
Asterisk server 10.17.0.240 doesnt ping 192.168/24 or 10.15/24

Those aren’t well formed, although I suppose it could infer the missing “.0”. To be well formed they would have to be either 10.15/16 or 10.15.0/24, depending on what your netmask really was.

both sub nets 10.15.0.1/24 and 10.17.0.1/24 have 255.255.255.0

My machine can ping every thing 192.168.0.102, not ping 10.17.0.240, 10.17.0.241 yes
The bosses machine 10.17.0.162 pings all and runs FreePBX at 10.17.0.240
I can talk to the phone on 10.15.0.201 wifi
the Asterisk (Sangoma Linux 7 v3.10) server 10.17.0.240 only pings 10.17.0.xxx

the FreePBX Sip NAT shows 10.15.0.0/24, 10.17.0.0/24 and 192.168.1.0/24
firewall trusts 10.15.0.0/24, 10.17.0.0/24, and 192.168.1.0/24

how do i get 10.15.0.xxx phone to talk to Asterisk server?
No prior experience and inherited the system. I add 10.15.0.0/24 to NAT and firewall everything else was allready there.

Did you restart Asterisk after changing the Asterisk SIP Settings? If not, try that.
