Yes they do; when we disable SRTP (Secure RTP) for the Gateway all Forwards not in the DID Range <b>Work</b> (this is the case for 3 different remote sites where CFwdAll doesn't work in the manner explained in my previous explanation)...Unfortunately I'm not the lead on this project and don't have access to configs, but let's assume when an IP Phone Caller calls out to the PSTN the Call are Encrypted between Phone and Gateway...<br>
