Sorry about the Delay. Let me try to clarify this more. I know it’s confusing and I apologize.
I have an office with one internet connection. It goes to a grandstream router gwn7000. There I created two subnets.
Default 192.168.1.0 with office wifi
Voip 192.168.20.0 with voip wifi.
I am able to keep every voip device on voip network with the exception of the users using their cell phones with gswave. I want all cell phones on the default network.
When they try to register to the ucm from the default to the voip network, it does not register.
If I put them (gswave cellphones) on the voip wifi , it works. Also, If I use only their mobile network, it works. But never works on the default Network wifi.
I placed a remote extension (gxp2130) on the default network (wired) and it registers to the ucm on the voip network.
I have another office with a ucm set up a few miles away. I figured I would try to see if I could get the gswave to register to that as an experiment. It registers on the default, voip, and cellphone mobile networks.
It would seem that only the gswave fails and only when I try to hairpin it from one vlan to the web and back on the other vlan.
Both networks can get to the web and I am able to access the ucm GUI (192.168.20.6) from either vlan.
I hope this helps. Sorry again for the delay on responding.
