Hi, I need to change some code of Asterisk. I want that change to make possible a preliminary estimation of latency when Asterisk receives an INVITE with SDP description to iniciate a session.
This estimation will be used to choose the most appropiated parameters for a determinated video codec ( i suppose that i know what client-program is being used so I know what codecs are supported). These parameters could be, for example, the resolution or the frame rate of video codec. Once the new parameters are been selected, the SDP description must be modified properly. Finally, an INVITE with the modified SDP description will be sent to the destination, For simplicity: I know what client is used so I know what videocodecs are resolution supported. In addition, i suppose that latency can be measure using "pings". So, any ideas to face this issue? Thanks, -- Juan I.
