Abstract: Voice service over a next generation network is provided using Advanced Intelligent Network solutions. A voice over network communications signal is communicated from an analog communications device over a telecommunications network to a softswitch (SSW) complex that detects and decodes a directory communications address to identify an internal, secret line number (SLN) communications address and, if associated with an SLN, to activate a voice over network application trigger to enable voice communications over an Internet Protocol, data communications network.

Abstract: During a telephone call, a transferring party performs an action to cause the telephone call to be transferred. The action causes a switch to send a query to a service control point (SCP) in a public-switched telephone network (PSTN). The SCP determines a transfer telephone number to which the telephone call is transferred. The transfer telephone number can be stored in a subscriber information table. The SCP determines the transfer telephone number and returns the transfer telephone number to the switch sending the query. The switch makes a telephone call to the transfer telephone number to cause a telephone associated with the transfer telephone number to ring. When the telephone associated with the transfer telephone number is answered, the transferring party disconnects from the telephone call to complete the transfer of the telephone call. A services node can also be used to determine the transfer telephone number.
