Teamed NICs and MAC addresses

We have a standard rule to team NICs on all of our physical servers.  However, the servers that host our phone software have a license tied to the MAC address of the NIC.  So, if we team the NICs, how will that impact this license if the primary NIC fails and the secondary NIC picks up?  Will the MAC address stay the same?  Will it change?

I'm asking because our phone tech is telling us to unteam the NICs and that will break our dual fabric redundancy we have set up in the switches.  

Can anyone shed some light on this?

Thanks

Cliff
