After a severe electrical storm zapped the supplied HUAWEI HG659, I bought a new modem. The modem is TP-LINK model TD-VG5612. Everything works fine, but I can't get VOIP to work. I've tried various registrar addresses such as aphone1.tpg.com.au, and tpgvoip.tpg.com.au, but with no success. Is this modem not compatible for VOIP? If so, can you supply me with a suitable modem. I've been a loyal TPG customer for many years. Thanks.
