The use of ciphers may impact the performance of the phone. Normal operation with the listed ciphers has been tested, but it is conceivable that certain combinations of ciphers, transports, RTP encryption, numbers of calls, codecs, audio paths, subscriptions, applications, etc., could result in audio degradation. If audio degradation is experienced, use alternate ciphers, transports, RTP, codecs, subscriptions, etc. |
