Patent ID: 8243720

Claim:
A method, comprising: providing information relating to an off-hook condition on an internet protocol telephone on a local internet protocol network to a time division multiplexing switch; creating an invite message by utilizing the internet protocol telephone; converting the invite message to a B bit toggle conforming to pulse code modulation robbed bit signaling at a voice over internet protocol channelized router, wherein converting the invite message is performed in response to the off-hook condition: providing the pulse code modulation robbed bit signaling to the time division multiplexing switch for a call between the local internet protocol network and a remote non-internet protocol network; signaling, by utilizing the pulse code modulation robbed bit signaling, a result of a conversion of internet protocol packets by a pulse code modulation robbed bit via the voice over internet protocol channelized router; terminating an internet protocol packet call to a digital signal 0 assignment using the voice over internet protocol channelized router; routing the internet protocol packet call to a hybrid internet protocol digital loop carrier system using the voice over internet protocol channelized router, wherein the internet protocol packet call is converted to a multiple digital signal 0 digital signal.
