[Freeswitch-users] Freeswitch srtp rejecting SRTP with 488

Wed Aug 20 02:31:38 MSD 2014

Hello Brian,
Thanks for your reply. I initially tried without the rtp_secire_media; I added rtp_secure_media = true after going through this page:
https://wiki.freeswitch.org/wiki/Secure_RTP
Probably I misunderstood it. So what is actually the issue and how to fix this. Please help ... Thanks in advanced!

Hi,
Below is my dialplan:
 <extension name="cext">   <condition field="destination_number" expression="^(2000)$">        <action application="set" data="rtp_secure_media=true"/>        <action application="bridge" data="user/bob"/>   </condition>   <condition field="destination_number" expression="^(3000)$">        <action application="set" data="rtp_secure_media=true"/>        <action application="bridge" data="user/bob"/>   </condition> </extension></context>

You can see I have rtp_secure_media=true for both extension. However, when I try to call I get rejected with 488 Not acceptable here.  In my freeswitch console log I find  sofia/internal/alice at 192.168.146.133 Standard REPORTING, cause: INCOMPATIBLE_DESTINATION. What should I do to fix this? 
Below is my complete console log:
