    Fundamentals Fundamentals VoIP makes the transmission of voice and telephony signalling via IP (“Internet Protocol”) possible. After a connection is established, the terminal collects voice data (PCM data), which is then sent to the receiver using an IP packet. PCM data can also be compressed to save bandwidth. Propagation Delay and Bandwidth IP-based data networks are generally not able to guarantee a specific minimum bandwidth and defined propagation delay.

    The SIP Internet (Session Initiation Protocol) protocol provides you with a low- cost, standardised option for telephoning via IP-based networks. The Forum 523/524 enables you to use external SIP telephone connections (“SIP trunk lines”). The Forum 523/524 communications system supports configu- ration of standard SIP lines with one call number for each as well as extension-capable SIP-DDI lines with base call number and extension.
