The greater the extent of impedance mismatch, the more leakage of transmit audio on the receive side of the line when it terminates …

It had been previously estimated by the VON Coalition, a VOIP industry consortium, that about two-thirds of VOIP users would have access to E-911 services by the deadline.…
