To answer my own question.
No voip available through AGL at this time. Couple this with some very average reviews about actual speed and service and I can't see the $10 per month saving as viable.
Hi @MrNeedHelp , VoIP is not currently available on AGL plans - that's correct.
It is planned and currently in the advanced stages of being rolled out, but I don't have an availability date to share at the moment.
