A method, Call Agent (CA), and circuit-switched terminal for setting up a multimedia session from the circuit-switched terminal toward a packet-switched terminal in a telecommunication network. An Instant Messaging (IM) server receives an IM message from the circuit-switched terminal and forwards the contents of the IM message to the CA. The CA generates or retrieves a unique call token that identifies the terminals, and sends the call token to the IM server, which forwards the token to the circuit-switched terminal. In response, the circuit-switched terminal initiates setup of a circuit-switched call to an identified Media Gateway Controller (MGC). The MGC then sets up a packet-switched session with the packet-switched terminal to complete the setup of the multimedia session.

Method and system for a communication session initialization in a telecommunication network

Methods are described for providing conference calls. Methods are performed in a conference call system and includes: receiving local contact information for a plurality of contacts stored in a local phone book of a user equipment associated with a caller; updating a contact database of the conference call system based on the local contact information; registering the caller with an interactive voice response system of the conference call system; receiving a spoken request from the caller; accessing the contact database with contact information and retrieving a phone number responsive to the spoken request; calling the retrieved phone number; and establishing contact between the caller and a person associated with the retrieved phone number. Systems and computer readable mediums are also described.
