Many calls dont come thru
Many calls dont come thru, but you cant hear anyone on the other side. I also hate the 2 second delay inbetween speaking.

I receive a number of calls that aren't even calls but I am charged for them, individually they aren't much but the total at the end of month adds up. In all fairness I just checked my billing history, and it looks like that has been fixed The faxing feature is not reliable, I have people try to fax me and the fax did come through and I had to send them to another fax number.

I always get the same amount of spam calls the same month. The system won’t allow you to block them. They just leave long messages that charge you by the minute. Kall 8 will get there monthly money based on these calls.

Overcharging for monthly standby numbers

I get calls for everything else but my customers. And I’m being charged almost $20 a month for it.
