<br>
I am using Asterisk 11.2. How do I choose the crypto suite for the
users registered in sip.conf.<br>
<br>
As I am new to SRTP, please let me know how this can be done<br>
<br>
Thanks and Regards,<br>

In general, the secure calling tutorial wiki page [1] can be a good
start for learning about TLS and SRTP in Asterisk.<br>
<br>
When it comes to SRTP crypto suites, you can set the
"encryption_taglen" option in sip.conf to either 80 or 32 in order
to use AES_CM_128_HMAC_SHA1_80 or AES_CM_128_HMAC_SHA1_32,
respectively. The default is 80.<br>
