I wanted to configure the maxis phone number to my IPPBX system so that i can route call to my SIP phone but i couldn't get it work even though connected to VLAN822 and able to get an IP Address from the DHCP server.

I tried live chat with the maxis support few days ago but he only gave me a contact number to call. When i call them up and after describe the issue to the customer support he requested me to hold and will transfer me to a tech guy to assist me but i waited more than 30 mins and until the line cut off also nobody get back to me.

Again, i called maxis help line on the day after. i explained to them the issue and they promise someone will get back to me within 2 hours but after 3 days still no one follow up and call me.

I wonder anything wrong with the maxis customer support ?

i believe custom router still able connect to the maxis data line as long as the VLAN ID has been configured properly. i'm using mikrotik router so far working fine.
