Does anyone have any information on why a Cisco 4431 (Cube) would not work with SRTP-RTP interworking?

Where did you get that from?

I also have an interworking issue but the issue only occurs when calls are CUBE->Provider->CUBE, if calls are TDM->Provider->CUBE then the calls interwork just fine. In both scenarios calls go to Unity Connection call handler and press menu option 1. In non-working scenario, after pressing 1 there is silence and call stays connected for some period of time with no SRTP interworking. IOS XE 17.6.3a

Hi, your problem doesn't sound like an RTP-SRTP interworking problem.
You have probably a DTMF problem.
If you would have an RTP-SRTP interworking problem, then normally the call wouldn't establish at all. But as you are reaching the call handler, the call establishes.
So, if you have problems, I would suggest you to open a new thread and provide more details, whats your setup, config, logs, ...

Hello, No, DTMF is fine, press 1, please wait while we transfer your call, then dead air and no encryption, no interworking. I have a TAC case open and ill update this thread when i get a resolution.
