System and method for establishing PSTN calls via an IP request
First Claim
1. A method of establishing a call over a Public Switched Telephone Network (PSTN), comprising:
- receiving a message from a calling party at a network element of a PSTN requesting establishment of the call over the PSTN using a callback feature, the calling party associated with a calling party'"'"'s consumer premises equipment (CPE) served by a first end office (EO) associated with the PSTN, said message being received via an internet protocol (IP) network and including identifying information for the calling party'"'"'s CPE;
notifying the first EO of the request for establishment of the call using the callback feature;
determining at least one of trunk and switch resources are available for the call at the first EO;
originating the call from the PSTN such that the first EO at least initially treats establishment of the call like a call terminating at the calling party'"'"'s CPE as opposed to a call originating from the calling party'"'"'s CPE;
applying an alerting signal to the calling party'"'"'s CPE; and
establishing the call from the calling party'"'"'s CPE to a called party'"'"'s CPE after the calling party'"'"'s CPE is answered in response to the alerting signal;
wherein the call originated from the PSTN is given a higher priority than other line originating call attempts to the first EO that wait for a dial tone and require digit collection.

15. A system for establishing a call over a Public Switched Telephone Network (PSTN), comprising:
-
a first end office EO associated with the PSTN and serving a calling party'"'"'s consumer premises equipment (CPE); and a network element within the PSTN configured to receive a message from a calling party requesting establishment of the call over the PSTN using a callback feature, the calling party associated with the calling party'"'"'s CPE, said message being received via an Internet protocol (IP) network and including identifying information for the calling party'"'"'s CPE; wherein the network element is configured to notify the first EO of the request for establishment of the call using the callback feature; wherein the network element, in cooperation with the first EO, is configured to determine at least one of trunk and switch resources are available for the call at the first EO; wherein the network element is configured to originate the call from the PSTN such that the first EO at least initially treats establishment of the call like a call terminating at the calling party'"'"'s CPE as opposed to a call originating at the calling party'"'"'s CPE; wherein the first EO is configured to apply an alerting signal to the calling party'"'"'s CPE; wherein the network element and first EO are configured to establish the call from the calling party'"'"'s CPE to a called party'"'"'s CPE after the calling party'"'"'s CPE is answered in response to the alerting signal; wherein the call originated from the network element is given a higher priority than other line originating call attempts to the first EO that wait for a dial tone and require digit collection. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A method of establishing a call over a Public Switched Telephone Network (PSTN), the method comprising:
-
at a network element of the PSTN, receiving a message from a calling party via an internet protocol (IP) network requesting establishment of the call over the PSTN using an enhanced automatic callback (EAC) feature, the calling party associated with a calling party'"'"'s consumer premises equipment (CPE) served by a first end office (EO) associated with the PSTN, said call between the calling party'"'"'s CPE and a called party'"'"'s CPE, the called party'"'"'s CPE served by a second EO associated with the PSTN, at least the called party'"'"'s CPE including a circuit-switched device, said message including identifying information for the calling party'"'"'s CPE and the called party'"'"'s CPE; at the network element of the PSTN, sending a Transaction Capabilities Application Part (TCAP) message to the second EO to provide notice of the request for establishment of the call using the EAC feature; determining the called party'"'"'s CPE is idle; at the second EO, sending a TCAP message to the first EO regarding the call indicating the called party'"'"'s CPE is idle; determining at least one of trunk and switch resources are available for the call at the first EO; determining intervening switches between the first EO and the called party'"'"'s CPE have enough capacity to complete the call; originating the call from the PSTN such that the first EO at least initially treats establishment of the call like a call terminating at the calling party'"'"'s CPE as opposed to a call originating from the calling party'"'"'s CPE; at the first EO, applying an alerting signal to the calling party'"'"'s CPE; making at least one of trunk and switch resources available across the PSTN from the first EO to the called party'"'"'s CPE for completion of the call; and establishing the call from the calling party'"'"'s CPE to the called party'"'"'s CPE after the calling party'"'"'s CPE is answered in response to the alerting signal using the at least one of trunk and switch resources made available across the PSTN; wherein the call originated from the PSTN is given a higher priority than other line originating call attempts to the first EO that wait for a dial tone and require digit collection.
