Will tunneling the sip/rtp packets be more common in the near future for SIP phone providers?

From the ITSP side (where we provide trunks). Tunnels would be a nightmare, so they are a no-no. Now you're throwing in too many variables (Aggressive, Main, set ups, different equipment). Not to mention the overhead it would add to an SBC.
From the Managed PBX side of the equation... NO, but before I ramble on, define tunneling. Tunneling as in VPN? If the concern is security, TLS is suitable from the managed PBX side as we can firewall trusted CIDRs on the firewall to prevent recording/tampering.
If you meant VPN tunneling... Would only work on a softphone because I have YET to see any VoIP device (phone, ATA, FXO, FXS) have any parameters to set up a tunnel. So I am unsure how one would truly call a VoIP Tunnel in a VPN sense, any kind of true tunneling.
