Hello, I've seen some desktop SIP phones (Snom, Yealink) intregrate a VPN (OpenVPN ?) client. Has someone experience to share about that particular feature ? Is this experience rather successful ? My underlying question is can one supervise and configure these desktop phones, in teleworking environment ? Is DHCP required ?

That can be configured just like you are used to do it with snom phones - DHCP, fixed IP, whichever you like. They also need a reachable NTP server. Then they will ( after booting) download the VPN config from your (hopefully protected) server and connect to the OpenVPN server. Address assignment on the VPN link is done by the OpenVPN internal mechanism. You will be able to reach the phone's web interface, afaik, both over its local address and the OpenVPN assigned one. Make sure to either have your PBX on the machine with the OpenVPN daemon or add appropriate route configuration to the OpenVPN client config. BR AMH

[asterisk-users] OT - Desktop SIP phone with OpenVPN client
Not sure why you'd say it's OT -- seems perfectly topical to me. Anyway, I have used the SNOM OpenVPN feature for remote clients. I'll be honest: it's a bit of a pain to set up and get working. This is triply true if the remote phone is moving around -- to the point that I'd strongly advise against it. But if it's staying in one place (e.g., a telecommuter's desk) once it's at the remote site, it should do the job, and reasonably well. It certainly can use DHCP, though I rather doubt it needs it -- not quite sure what you're angling for by way of your question. WiFi was a PITA; I'd advise against. (Esp. since -- at least, at the time -- you needed to download beta firmware to get both WiFi and OpenVPN working at the same time.) Note that I haven't touched this in about two years' time, so things may have changed a bit in the interim. -Ken On 2013-01-21 08:21, Olivier wrote:> Hello, > > I've seen some desktop SIP phones (Snom, Yealink) intregrate a VPN > (OpenVPN ?) client. > > Has someone experience to share about that particular feature ? > Is this experience rather successful ? > > My underlying question is can one supervise and configure these > desktop phones, in teleworking environment ? > Is DHCP required ? > > Regards > > -- > _____________________________________________________________________ > -- Bandwidth and Colocation Provided by http://www.api-digital.com -- > New to Asterisk?
