Does anyone using SME maxis plan?

My current setup is WDR4300 + echolife hg8240.

But i've lost the VOIP function.

I've been trying all the methods listed in this thread, but none was working, even tried to setup SIPdroid in my phone, i'm unable to connect too.

Maybe someone could enlighten me on this.

I just want to get the VOIP work, either through the HG8240. or thru an software VOIP.

Mind that package i signed up was for SME, so the settings might be different.

I've just upgrade my plan from 30mbps to 100mbps.
and changing my router to ubiquiti edgerouter-x to have a more stable connection.

apparently they did something tricky again.
initially i just do all the VLAN stuff, and get it connected, but the speed is limited to like 5mbps up/down. tried to switched back to thomson router, it back to 100mbps.

Then I suspect they lock the MAC address of the router, spoofed my EdgeRouter-X port Mac address same as Thomson router and it works fine! getting 100mbps up down.
