The callee receives the INVITE message with the RTP encryption algorithm. The callee
answers the call and responses with a 200 OK message carrying the negotiated RTP
encryption algorithm.
The example of the RTP encryption algorithm carried in the SDP of the 200 OK
message for reference:
m=audio 11780 RTP/SAVP 0 101
a=rtpmap:0 PCMU/8000
a=rtpmap:101 telephone-event/8000
a=crypto:1 AES_CM_128_HMAC_SHA1_80

You can configure the SRTP feature on a per-account basis. When SRTP is enabled on
both IP phones, the RTP streams will be encrypted, and a lock icon appears on the
LCD screen of each IP phone after the successful negotiation.
