---------------------------------------------------------------------- 
Hello all, I'm trying to use SRTP in Asterisk with a Twinkle phone. I've
done all the steps given in
http://www.voip-info.org/wiki/view/Asterisk+SRTP. I've built the SRTP
library and then I've get asterisk from
https://svn.digium.com/svn/asterisk/team/group/srtp and I've built it. Then
I've modified my sip.conf and my extension.conf in this way

sip.conf

[9000]
type=friend
qualify=yes
secret=guessthis
nat=no
host=dynamic
canreinvite=no
context=phones
srtpcapable=yes

extension.conf

exten => 9000,1,Set(_SIP_SRTP_SDES=1)
exten => 9000,n,Set(_SIPSRTP=enable)
exten => 9000,n,Set(_SIPSRTP_CRYPTO=enable)
exten => 9000,n,Dial(SIP/9000,30,Tt)
exten => 9000,n,Hangup()

I don't know how to view if the call is encrypted or no. Asterisk don't
return any message about if the call is encrypted or no.I've used the
wireshark to view the frames but I can't view nothing about crypto.

Thank you in advance
