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!

Subject: Freeswitch srtp rejecting SRTP with 488
Date: Wed, 20 Aug 2014 03:22:03 +0600

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@192.168.146.133 Standard REPORTING, cause: INCOMPATIBLE_DESTINATION. What should I do to fix this? 

Below is my complete console log:
