Just got the model Dlink DSL-G2452DG, managed to configure the wifi and internet successfully but the Voip is still not working
Do you have any idea? See my settings on the WAN and VOIP

That means to say the settings shown in the pictures should be correct, just need to get the phone number and password correct?

i managed to get the router working on the internet and voice.

However, i realized some issues with the Dlink

1. After 48 hours of usage, the wireless router will lose connection to the maxis internet (no internet access after 48 hours). Need to reboot to fix
2. After each reboot, sometimes , the voice will not come up until you toggle the Service Type settings on Eth3_1 between TR069_VOIP and VOIP

Do you guys have these issues?

thanks
