Electronic bridge between mobile-telecommunication device and public-switched-telephone-network (pstn) or voice-over-internet-protocol (voip) device

A method, comprising:

• receiving, with a first telephone, a voice-device identifier from a second telephone that is disconnected from a telecommunication network;
• calling, with the first telephone in response to the voice-device identifier, a voice device over a telecommunication network;
• receiving, with the first telephone, a first voice signal from the second telephone;
• providing, with the first telephone, the first voice signal to the voice device over the telecommunication network.

A method, comprising:

• receiving, with a bridge circuit, a voice-device identifier from a first telephone that is disconnected from a telecommunication network;
• causing, with the bridge circuit in response to the voice-device identifier, a second telephone to call the voice device over a telecommunication network;
• coupling a first voice signal from the first telephone to the second telephone;
• and
• coupling, with the second telephone, the first voice signal to the voice device over the telecommunication network.

A system, comprising:

• a first telephone that is disconnected from a telecommunication network;
• and
• a bridge circuit configured
• to receive a voice-device identifier from the first telephone,
• to cause a second telephone connected to a telecommunication network to connect to a voice device via the telecommunication network in response to the voice-device identifier,
• to route a first voice signal from the first telephone to the voice device via the second telephone and the telecommunication network, and
• to route to the first phone a second voice signal that the voice device sends to the bridge circuit via the telecommunication network and the second telephone.

A non-transitory computer-readable medium storing instructions that, when executed by a computing apparatus, causes the computing apparatus, or one or more circuits under control of the computing apparatus:

• to receive a voice-device identifier from a first telephone;
• to cause a second telephone connected to a telecommunication network to connect to a voice device via the telecommunication network in response to the voice-device identifier;
• to route a first voice signal from the first telephone to the voice device via the second telephone and the telecommunication network;
• and
• to route to the first phone a second voice signal that the voice device sends to the bridge circuit via the telecommunication network and the second telephone.
