Network Configurations

The UDP port used for RTP streams is traditionally an even-numbered port. If the port 11780 is used to send and
receive RTP for the first voice session, additional calls would then use ports 11782, 11784, 11786, and so on. The
phone is compatible with RFC 1889 - RTP: A Transport Protocol for Real-Time Applications - and the updated RFC
3550.
