An intermediate report: *Audiocodes*: TLS works only on outgoing requests, incoming ones are ignored. I am waiting for Audiocodes' help in order to debug it. SRTP: worked when no TLS is active. When TLS is active the call is disconnected when the remote party answers. Still debugging it. *VegaStream Europa-50*: SRTP works. Waiting for Vega for instructions how to enable TLS from the WEB interface. Regards, __Yehavi: 2009/12/4 Yehavi Bourvine <yehavi.bourvine@gmail.com>
I'll report when I am done.
So far I've enabled only SRTP and both support it.

Thanks Yehavi,
I would be very interested to find out how your test goes... can you report back after you have tested it?
Thanks!

Hello,
I have AudioCodes MP and Vega ATA adapters. They both support SRTP; they should support TLS also (will try it next week; up to now I preffered to not use TLS so I can sniff the traffic and debug things).

Cheers Gabriel.. thanks for the information.
I'll look at the Mediatrix ATA's as an alternative - has anyone had experience with those and TLS/SRTP?

The ATAs I'm aware that claim support for TLS and SRTP w/ SDES are
the
Grandstream and Mediatrix devices (although I've never tried either one with FreeSWITCH).
I've personally never had any good experience with the Grandstream ATAs. The Mediatrix ATAs are OK devices, but I've never personally tested them with SRTP w/SDES and FreeSWITCH, but supposedly they support it (so says their marketing material and docs).
I'd see if Cisco has any plans to add support for it to the ATAs. Next time I see our Cisco SE, I'll try to poke him about it.

Quote: Cisco/Linksys SPA series ATAs do not support SDES key exchange to appropriately support SRTP and FreeSWITCH
I'll check with Cisco regarding their implementation then and try to find out when/if they will support standard SRTP encryption.
So, back to my origianal question then. Are there any ATA's that support TLS AND SRTP with FreeSwitch?
