    initial v1  
    1 Known issues: 
    2  1. We reject SDP session offer containing three media (in SRTP mandatory mode?): 
    3     a. normal active media with RTP/SAVP & crypto 
    4     a. deactivated media (port 0) with RTP/SAVP without crypto 
    5     a. active media with RTP/AVP 
    6  2. We reject "m=video 0 RTP/AVP" with PJMEDIA_SDP_EINPT (notice port 0 and no fmt). 
     1Scenario: 
     2    a. In SRTP mandatory mode, call established with 2 media: active audio with SRTP enabled and inactive video (port 0). 
     3    a. Remote send re-offer with three SDP media lines: audio with RTP/SAVP+crypto, deactivated video (port 0) with RTP/SAVP without crypto, audio with RTP/AVP without crypto. 
     4    a. We reject the re-INVITE with 488 (actual error code PJMEDIA_SRTP_ESDPREQCRYPTO). 
     5 
     6It should not be rejected as the first media in the reoffer is actually acceptable.
