Endpoints are Innovaphone IP810 telephone system, registered as gateway,<br>
and Innovaphone IP241 phone wich is calling e.g. Tetris via this gateway.<br>
<br>
In my dialplan I have set <action application="export"<br>
data="rtp_secure_media=mandatory:AES_CM_128_HMAC_SHA1_80,AES_CM_128_HMAC_SHA1_32"/><br>
With AES128, I can hear Tetris.<br>
<br>
When I change this to "AES_CM_256_HMAC_SHA1_80", which I would prefer, I<br>
hear nothing.<br>
<br>
In the file mime.types I see only "audio/rtp-enc-aescm128".<br>
<br>
Do you need more information?<br>
