Yealink SIP-T19 E2 — настройка RTP портов для IP-телефонов: руководство администратора [626/841]

Administrator’s Guide for SIP-T2 Series/T19(P) E2/T4 Series IP Phones

610

The Real-time Transport Protocol (RTP) is a network protocol for delivering audio and

video over IP networks. The UDP port used for RTP streams is traditionally an

even-numbered port. For example, the default RTP min port on the IP phones is 11780.

The first voice patch sends RTP on port 11780. Additional calls would then use ports

11782, 11784, 11786, etc up to the max port.
