Abstract

A method is provided for causing a networking device to enter a power saving mode, determining whether or not a Voice over Internet Protocol (VOIP) telephony interface is in service after the causing the networking device to enter the power saving mode, the networking device including the VOIP telephony interface, the VOIP telephony interface communicatively connected to a VOIP provider, and rebooting the networking device when the VOIP telephony interface is determined not to be in service.

First claim

1 . A networking device comprising:
a processor; a Voice over Internet Protocol (VOIP) telephony interface configured to communicate with the processor; and a non-transitory memory having executable instructions stored thereon, which when executed, cause the processor to perform:
causing the networking device to enter a power saving mode;
determining whether or not the VOIP telephony interface is in service after the causing the networking device to enter the power saving mode, the VOIP telephony interface being communicatively connected to a VOIP provider; and
rebooting the VOIP telephony interface when the VOIP telephony interface is determined not to be in service.

2 . The networking device according to claim 1 , wherein the determining whether or not the VOIP telephony interface is in service includes obtaining an operational state of the VOIP telephony interface,
wherein when the operational state of the VOIP telephony interface indicates that the VoIP telephony interface is operational, the VOIP telephony interface is determined to be in service, and wherein when the operational state of the VOIP telephony interface does not indicate that the VoIP telephony interface is operational, the VOIP telephony interface is determined to not be in service.

3 . The networking device according to claim 1 , wherein the determining whether or not the VOIP telephony interface is in service includes obtaining an operational state of the VOIP telephony interface,
wherein when the operational state of the VOIP telephony interface indicates that the VOIP telephony interface is operational, the VOIP telephony interface is determined to be in service, wherein when the operational state of the VOIP telephony interface does not indicate that the VOIP telephony interface is operational and when the determining of whether or not the VOIP telephony interface is in service has been performed less than a predetermined number of times, the determining of whether or not the VOIP telephony interface is in service is repeated, and wherein when the operational state of the VOIP telephony interface does not indicate that the VOIP telephony interface is operational and when the determining of whether or not the VOIP telephony interface is in service has been performed a predetermined number of times, the VOIP telephony interface is determined to not be in service.

4 . The networking device according to claim 1 , wherein the processor causes the networking device to enter the power saving mode when (i) power supplied to the networking device is interrupted or (ii) data traffic of the networking device is below a threshold for a predetermined amount of time.

5 . The networking device according to claim 1 , wherein the rebooting the VOIP telephony interface includes obtaining an IP address of a server of the VOIP provider and transmitting a registration request to the server of the VOIP provider.

6 . The networking device according to claim 1 , wherein the processor further performs notifying a telecommunications device that the VOIP telephony interface is in service when the VOIP telephony interface is determined to be in service, the telecommunications device being connected to the networking device.

7 . The networking device according to claim 1 , wherein the processor further performs notifying a telecommunications device that the VOIP telephony interface is in service after rebooting the VOIP telephony interface, the telecommunications device being connected to the networking device.

8 . The networking device according to claim 1 , while in the power saving mode, the networking device only operates a single transmit channel for transmitting data and a single receive channel for receiving data.

9 . The networking device according to claim 8 , wherein the single transmit channel for transmitting data and the single receive channel for receiving data are reserved for data transmission and reception for the VOIP telephony interface.

10 . A method comprising:
causing a networking device to enter a power saving mode; determining whether or not a Voice over Internet Protocol (VOIP) telephony interface is in service after the causing the networking device to enter the power saving mode, the networking device including the VOIP telephony interface, the VOIP telephony interface communicatively connected to a VOIP provider; and rebooting the networking device when the VOIP telephony interface is determined not to be in service.

11 . The method according to claim 10 , wherein the determining whether or not the VOIP telephony interface is in service includes obtaining an operational state of the VOIP telephony interface,
wherein when the operational state of the VOIP telephony interface indicates that the VoIP telephony interface is operational, the VOIP telephony interface is determined to be in service, and wherein when the operational state of the VOIP telephony interface does not indicate that the VoIP telephony interface is operational, the VOIP telephony interface is determined to not be in service.

12 . The method according to claim 10 , wherein the determining whether or not the VOIP telephony interface is in service includes obtaining an operational state of the VOIP telephony interface,
wherein when the operational state of the VOIP telephony interface indicates that the VOIP telephony interface is operational, the VOIP telephony interface is determined to be in service, wherein when the operational state of the VOIP telephony interface does not indicate that the VOIP telephony interface is operational and when the determining of whether or not the VOIP telephony interface is in service has been performed less than a predetermined number of times, the determining of whether or not the VOIP telephony interface is in service is repeated, and wherein when the operational state of the VOIP telephony interface does not indicate that the VOIP telephony interface is operational and when the determining of whether or not the VOIP telephony interface is in service has been performed a predetermined number of times, the VOIP telephony interface is determined to not be in service.

13 . The method according to claim 10 , wherein the causing the networking device to enter the power saving mode is performed when (i) power supplied to the networking device is interrupted or (ii) data traffic of the networking device is below a threshold for a predetermined amount of time.

14 . The method according to claim 10 , wherein the rebooting the VOIP telephony interface includes obtaining an IP address of a server of the VOIP provider and transmitting a registration request to the server of the VOIP provider.

15 . The method according to claim 10 , further comprising notifying a telecommunications device that the VOIP telephony interface is in service when the VOIP telephony interface is determined to be in service, the telecommunications device being connected to the networking device.

16 . The method according to claim 10 , further comprising notifying a telecommunications device that the VOIP telephony interface is in service after rebooting the VOIP telephony interface, the telecommunications device being connected to the networking device.

17 . The method according to claim 10 , while in the power saving mode, the networking device only operates a single transmit channel for transmitting data and a single receive channel for receiving data.

18 . The method according to claim 8 , wherein the single transmit channel for transmitting data and the single receive channel for
