Ive tried setting up sipdroid using my VOIP/SIP details which are currently setup and working via 'normal' phone connected to my VOIP modem... I put in all the same details for the sipdroid settings, it looks like its gonna work, dial a number but it doesnt connect. Any thoughts?? I know my wifi works fine.... and also I have to uninstall sipdroid so I can use my phone as per normal..?? Phone is a HTC Magic.
