Anyone have experience with encrypting voice? I need to encrypt RTP from a SIP conference phone IP 7000 (polycom) to ShoreTel phones.
ShoreTel is setup for SRTP AEN 128bit and I have the IP 7000 setup with SRTP. I know Shoretel only encrypts on network calls and strips the encryption on trunk, TDM, and SIP calls, so I need a device that will except encryption from ShoreTel and rebuild the encryption to what the IP 7000 is looking for and back the other way, IP 7000 rebuild and send to Shoretel.
I'm able to ring the ShoreTel phones with encryption turned on both the IP 7000 and ShoreTel, but the call doesn't connect when answered. I'm close, but need a device in between the two I think.
Any info on what device might handle this would be greatly appreciated.

Unless the shoretel is using it's own proprietary implementation then you should be able to use SIP over TLS and SRTP from the Polycom to the shoretel. Perhaps you just need to look into the provisioning documentation further to find the right settings.

Otherwise I don't know of much of anything that will work if it's not standards-based. That's why I don't like proprietary.

If the polycom cannot do encryption such as SRTP then the "encryption device" would have to be a VPN router. These can be had at your local Best Buy cheap or you can get a more expensive Cisco, etc.
