Here is my scenario. I have a Sonicwall with LAN 192.168.16.x with a VLAN(VOIP)of 10.10.20.X The PBX has a 192.168.16.X IP
The ISP just installed a ESBC on the network and I gave it a 192.168.16.x IP. I was told that the PBX had to use the ESBC as its gateway, however by doing that the VLAN or IP phones are unable to see the PBX.
What would be the best way to handle this?
