Different problem, but voice mail issue still: I have VBuzzer registered with my Voxalot account, but when I try to call my
username@vbuzzer.com:80 using Gizmo Project, to see if it gets forwarded to my ATA alright, it goes directly to Vbuzzer voice mail. The Vbuzzer computer voice tells me the user at extension ###### (which is my Voxalot account number) is not available and to please leave a message. Apparently VBuzzer is hard to configure even with an ATA, but I know in my Voxalot provider plan I did do the correct thing of saying my proxy is vbuzzer.com and the port is 80 (not 5060 as normal). So I think Voxalot needs to tweak a setting on its end as well.
No problems: I can confirm that FWD, FreeDigits, and Gizmo Project all work perfectly as SIP providers to register with through Voxalot's new registration feature, so that calling my SIP address for each of these three all ring my ATA. :-)
