1. A method of establishing a modem connection link from a public switched telephone network modem to an alarm processing system comprising:
- coupling an alarm data generated from an alarm system to a sending modem;
coupling the sending modem to an analog telephone adapter to transmit the alarm data,coupling the analog telephone adapter to a first internet connection of an IP network,receiving the alarm data from the first internet connection of the IP network and communicating the alarm data to a media gateway, the media gateway capable of supporting an HTTPS protocol and further capable of interfacing to the public switched telephone network;
monitoring, by an analog telephone adapter timer control module in conjunction with a timer sequencer module, one or more unique data fields for a live time communication;
receiving the alarm data from the media gateway and transmitting the alarm data to a receiving modem of a receiving computer system via the public switch telephone network so that the alarm company computer system receives the alarm data;
monitoring, a reception, a complete transmission and verifying an accurateness of reception of the alarm data at the receiving computer system;
transmitting the live time communication, controlled by the analog telephone adapter timer control module in conjunction with the timer sequencer module;
sending a series of RTP/SIP messages from the analog telephone adapter through a firewall to the IP network, the media gateway, the public switch telephone network and the receiving modern of the alarm processing system, where a reply RTP/SIP message, returned back from the receiving modem updates a controlling component of the analog telephone adapter and the media gateway regarding the status of the live time communication; and
synchronously controlling the live time communication;
occurring between the analog telephone adapter and the receiving modem of the receiving computer system.

Abstract
An apparatus and method for computer telephony communications, specifically for interconnecting legacy modem devices using an analog telephone adapter (ATA). A modem connection link is established from a PSTN modem device having an ATA device that may be connected to a IP transport medium (internet), where the IP transport medium is connected to a media interface and where the media server is also connected to a PSTN modem device with full data integrity, so that there is a successful data delivery via the PSTN modem.
