Please add support@voipo.com and sales@voipo.com to your whitelists if you use SPAM Filtering.

There are also a lot of people we're seeing using like BoxTrapper or other SPAM systems that require us to reply to verify that we're real. In those cases, you definitely need to whitelist since our system won't know to reply.

We're seeing a lot of cases with emails not being delivered or faxes not going through and in most cases, this is what it's turning out to be.

Thanks for your cooperation.
