how fast is the process time compare in occ and phone call though?

Dear all sifus,

I urgently need help!!!

My company is currently subscribe to unifibiz 20 for the office usage. Surprisingly TM is giving a lousy router that is similar to home router.

I have successful replaced the router with Fortigate 80C, by creating vlan ID 500 in WAN connection. All internet connection work properly.

The problem now is that the unifi voice ( phone number that comes with unifi package) doesn't work properly, it can only make outgoing call but no incoming call. The line always engage when someone call from outside. I read somewhere saying that we need to create vlan Id 400.

Anyone has encounter this? Or anyone can help/guide me on how to do this ?

Thanks

Hi Xefron,

thanks for your reply.

my current setup is creating a vlan with vlan ID 500 in fortigate WAN port (by using the static IP and login info) .  Modem-> Fortigate-> internal network.
for Option 1, Do you means to use the Isp router as below:

Modem -> TM Router-> fortigate -> internal Network ?

if follow the setup above, how do i configure the TM Router, like those IP settings, cabling connection and etc...

Thanks a lot for your help..
