Patent ID: 8605620

Claim:
A method for transmitting data signals in a communication connection from a communication first device to a second communication device over an Internet Protocol (“IP”)-based network, comprising: transmitting data packets from a first communication device to a second communication device via said IP-based network using a first transmission protocol that does not retransmit transmitted packets that are at least one of lost and damaged; determining that network performance of said IP-based network is insufficient to transmit quality data signals using the first transmission protocol; changing from transmitting data packets using the first transmission protocol to transmitting data packets using a second transmission protocol that provides for retransmission of transmitted packets that are at least one of lost and damaged; generating an indication that identifies a missing packet; transmitting a signal to said first communication device requesting retransmission of said identified missing packet; determining that said communication connection serves a speech-based application that requires high quality audio signals; activating, in response to said step of determining, said IP-based network to transmit said high quality audio signals without transcoding; and determining presence of the second communication device on said communication connection that requires high quality audio signals.
