Method and system for providing a continuous tone source using a network node

A system for providing a continuous tone in voice communication networks, comprising:

• a switch configured to follow call routing/switching instructions;
• and
• a network node including a first service logic program to provide the call routing/switching instructions and a second service logic program to provide the continuous tone to the switch,
• wherein the switch is to receive an incoming call from a calling party and is to forward the incoming call to the network node,
• wherein the network node is to receive the incoming call from the switch, to place an outgoing call to a called party in response to the incoming call, to connect the incoming call and the outgoing call, and to transfer the connected incoming call and the outgoing call to the switch,
• wherein, during the transfer, when the network node is to direct the switch to place the incoming call and the outgoing call on hold, the second service logic program in the service node is to provide the continuous tone to the connected incoming call and outgoing call on the switch through a permanent trunk line configured to pass the continuous tone from the service logic program, and
• wherein, after the transfer, the network node is only connected to the switch through the permanent trunk line.

A method for providing a continuous tone to parties of a voice call, comprising:

• receiving an incoming call from a calling party;
• placing an outgoing call to a called party in response to the incoming call;
• connecting the incoming call and the outgoing call;
• and
• transferring the connected incoming call and the outgoing call,
• wherein, during said transferring, a call routing service logic program directs the switch to place incoming call and outgoing call on hold and a service logic program provides a continuous tone to at least one of the incoming call and outgoing call through a permanent trunk line connected from the service node to the switch, and
• wherein, after the transfer, the network node is only connected to the switch through the permanent trunk line.

A computer-readable medium containing software code that, when executed by a computer, causes the computer to execute a method to provide a continuous tone to one or more parties of a voice communication call, the method comprising:

• receiving an incoming call from a calling party of the call to a called party of the call;
• forwarding the incoming call to a call routing service logic program on a service node;
• receiving, in a transfer from the service node, the incoming call and an outgoing call,
• wherein, during said transferring, when a network node directs a switch to place the incoming call and the outgoing call on hold for a duration of at least one second, a service logic program is to provide the continuous tone to at least one party selected from a group consisting of the calling party and the called party through a permanent trunk line connected from the network node to the switch, and
• taking the incoming call and the outgoing call off hold when the transfer is complete and disconnecting the at least one call from the continuous tone service logic program,
• wherein, when the transfer is complete, the network node is only connected to the switch through the permanent trunk line.

A computer-readable medium containing software code that, when executed by a computer, causes the computer to execute a method to provide a continuous tone to one or more parties of a voice communication call, the method comprising:

• receiving an incoming call having a calling party and a called party from a switch;
• placing an outgoing call to the called party;
• transferring the incoming call and the outgoing call to said switch, wherein the incoming call and the outgoing call are placed on hold during said transferring;
• and
• providing a continuous tone to at least one party selected from the group consisting of the calling party and the called party while the incoming call and the outgoing call are on hold for a duration of at least one second,
• wherein, during said transferring, a network node is to direct the switch in communication with the network node to place a call on hold for a duration of at least one second, a service logic program is to provide the continuous tone to at least one party selected from a group consisting of the calling party of the call and the called party of the call while the call is on hold and while connecting the calling party to the called party to complete the call through the switch,
• wherein, during said transferring, when a network node directs a switch to place the incoming call and the outgoing call on hold for a duration of at least one second, a service logic program is to provide the continuous tone to at least one party selected from a group consisting of the calling party and the called party through a permanent trunk line connected from the network node to the switch, and
• wherein, when the transfer is complete, the network node is only connected to the switch through the permanent trunk line.
