http://www.voxalot.com/action/tutorial?itemOID=68 says that I should be able to make a SIP URI call to my Voxalot number, but I can't. I've tried dialing xxxxxx@au.voxalot.com but it goes to voicemail (which I have disabled by the way - go figure!) rather than ringing my ATA.
My ATA is a SPA3000 which has my Voxalot account registered on the PSTN tab (I have a different VSP registered on the Line 1 tab so I can receive calls on that VSP's DID).
Does anyone know why the SIP URI dialing doesn't work? I'm calling it from a softphone on my PC which is registered to a different VSP.
