Hello In case a NAT firewall prevents using STUN to open SIP/RTP ports, a solution is to first connect the phone to the Asterisk server through a tunnel, and then have data go through the tunnel. Are there hardphones that support OpenVPN? If none, what about SSH? Is this a good alternative to use VoIP with SIP? If you've tried either or both solutions, I'm interested in any feedback. Thank you.

Hi Gilles, You can't tunnel UDP through SSH. Some of the newer Grandstream handsets support OpenVPN and are a bit cheaper than the Snom alternatives. - Regards, AJ Stanfield t: 0161-850-4001 e: aj at dmcip.com w: http://www.dmcip.com ----- Original Message ----- From: "Gilles" <codecomplete at free.fr> To: asterisk-users at lists.digium.com Sent: Tuesday, 31 January, 2012 12:32:20 PM Subject: [asterisk-users] [NAT] SSH vs. OpenVPN?

Bummed that it seems to only support one tunnel, though. I asked their support team if they could make whatever changes necessary to support multiple, and their response made it sound promising :) I love this phone, actually. j

Multiple tunnels are for conference calls?
