I'm trying to connect my Nokia N80ie to my modem for the use of voip over Wlan. But it won't register. I have a geografic SIP-number from my ADLS provider(Tiscali). That number works fine with de Zyxel modem I use. Wired via modem and via a Sofphone(Xlite) on my PC.
I've read about XLM files and the Nokia voip client not capable enough, etc.... But I'm not technical enough to make this happen!!!!! Can you refer me to somebody who has expirience with this matter.
