More importantly, it would be nice to be able to disable certain numbers or block outgoing numbers that we assign like 411 for me since I never use it and would rather not be charged for this service erroneously or otherwise. I'm not sure how it would work with a service type of number like that or even needed by the average person but I just thought I'd throw it out there. Sort of like how ooma automatically blocks 900 or 976 number dialing. Or even with how we can blacklist incoming, how about being able to blacklist outgoing....say your teenage daughter's boyfriend who you don't like's number for example haha.
Do they charge only if they help you or is it as soon as it goes through regardless of whether you request assistance or not?
In general (and I do not know ooma's policy for sure) you are only charged once the call is connected. Sometimes there is a 10 second or so time lag between call connection and the start of billing.
Once again, I don't know ooma's policy, just thinking generally here
