At the moment, the only way I've been able to get an incoming call to work from Voxalot / SipBroker is by registering my ATA as a "provider" in my Voxalot setup (entering my ATA's IP address, and a dummy username and password).

I've confirmed that this workaround works.
At e164.org, my PSTN numbers are mapped to my VoXaLot SIP URI
6xxxxx@au.voxalot.com
and in Voxalot, I've got all calls forwarded, via my "provider" to 050xxxxxxxx. My "provider", of course, is just my ATA (ie in the provider details page, I've put my public IP address in as the host, and entered a dummy username and password (my ATA doesn't ask for them).
The calls get through OK, but the media stream is being proxied by Voxalot. Similar to web callback, it looks like Voxalot is implementing call forwarding via providers as a "back to back user agent" arrangement.
On the plus side, that gives me automatic transcoding if necessary (my ATA only does G711 u-law), however on the minus side, it causes the voice traffic to transit voxalot which may increase latency.
