A process for manufacturing a wafer having a multiplicity of MEMS devices such as mirrors with gimbals formed thereon is disclosed. A data channel connection with the telephone handset may provide pre-call information used to set up incoming and outgoing calls which are ultimately connected using a voice channel. The method further includes issuing, automatically based on the establishing, unique credentials to the agent. Output portions of first inverters are coupled together through a first wiring; and output portions of second inverters are coupled together through a second wiring. Each of the conductor filling material and wire filling material is inert, non-flammable and able to withstand a temperature of at least approximately 200\xb0 C.
