Abstract
A method for establishing a call in a telecommunications network that has first and second packet network sections, a wide area packet network, and a TDM transit network section. Subscribers'terminal equipment is addressable by directory numbers, and calls to subscribers are always routed through the TDM transit network. During TDM call setup at least one message or information element is conveyed to the second packet network section which is indicative of the first terminal equipment's packet capabilities and/or an address of a first controlling device controlling the call in the first packet network section. The message or information element is received at a second controlling device controlling the call in the second packet network section. Using the information extracted from the message or information element a second connection between the first and second terminal equipment through the wide area packet network is established by the controlling devices.
