SRTP has gained a lots of interest in the last few weeks and some of my
clients are requesting it. I was not aware of multiple encryption options
for SRTP, but it will be nice to be ready to face every kind of encryption

>   I'm currently testing support for AES_GCM_128_8 with pjsip and
> FreeSWITCH (it works).  I'd love to add Asterisk to this list.  I'm
> working on a patch (I just can't seem to get chan_sip to prefer
> AES_GCM_128_8) but in the meantime I thought I'd check with the list
> to see if there's any interest or work done on this already.
> Thanks!
