<div dir="ltr"><div><div><div>Hi Mike,<br><br></div>Actually I'm not. This is a request from my local operator. As you said I told them that is possible to encrypt entire rtp stream by SRTP / ZRTP techniques. She says me that (on Huawei Switch) the encryption option just there when she selects rfc2833 for digit handling and not on entire media stream !!! <br>

I'm not familiar with a standard that just encrypts the dtmf. Did they provide any details of what this standard is?<br>
