Free Long Distance Voip

I’m trying to lower the costs of land-line & cell phone service but still keep it for basic service & emergencies.

I’m in the process of applying for “telecommuting” call-center jobs, but as their systems don’t work with cell phones or VoIP, (which MagicJack technically is) & as MJ is not compatible with alarm systems, satellite etc.,& MJ recommends an emergency backup for 911, I’ll still need to keep the land-line phone.

But all the landline plans are minimum $40-$50 monthly, as they all include features like call waiting, caller ID, etc. which the jobs I need it for, don’t even allow.

As I’ll be using MJ for all non-work calls, I just need the CHEAPEST basic service with a flat rate unlimited local & long-distance calls (for work). No frills or fancies.

I’m in metro-Detroit. Anyone know the CHEAPEST land-line plans for $30 or under – just for work & emergencies??
