• Allow Secure => This will allow Secure RTP and Non-Secure RTP

NOTE:
3CX doesn't support crypto 3-8, 9-11 (only support crypto 1 and 2)
• Configuration:
• No RTP encryption is needed - Set "Normal" on the PBX and disable it on the phone
• RTP encryption is needed - Set "Only Secure" on the PBX and Mandatory (Compulsory)
on the phone
• The option "Allow Secure" that we have on the PBX, is used only for the 3CX clients.
• 3CX does NOT support negotiation for SRTP/RTP with hard phones. For a J100 phone, users
must pick either forced RTP or forced SRTP (set media encryption 9 for RTP, media encryption
1 or media encryption 2 for SRTP)
