There hasn't been any changes as far as I can tell.....incoming calls to the VoXalot SIP URI
123456@voxlaot.com (where 123456 is your acct number) are still working fine...
-Check that your IPKall number has not expired by logging in
-Freedigits has had issues lately so I wouldn't be surprised if it isn't working
-Have GC/GV forward to the IPKall number...
