OpenVPN and DNS Servers

[_DJ]

Hi,

How are phones connected with OpenVPN supposed to work with DNS Servers?

My assumption was that the phone will first start to initiate an OpenVPN connection if possible. If successful and DNS servers are pushed by the OpenVPN server, the phone will use these DNS servers as the preferred over the DNS servers first received from the initial DHCP on the LAN.

Then these DNS servers pushed by OpenVPN will be used for resolution of

- Autoprovisioning Server
- SIP Server
- Outbound Proxy Servers

However I am finding that even connecting to OpenVPN the DNS servers pushed by DHCP are used for resolution of the above.

Could you please confirm this

I've tried this with a T40P

Firmware Version 54.82.0.20

also with a T23G

Firmware Version 44.82.0.20

Here are some of the settings I am using

auto_provision.dhcp_option.enable = 1
account.1.outbound_proxy_enable = 1
account.1.sip_server.1.address = sip.xxx.net
account.1.outbound_proxy.1.address = sipproxyc.xxx.net
account.1.outbound_proxy.2.address = sipproxyd.xxx.net
account.1.outbound_proxy.1.port = 0
account.1.outbound_proxy.2.port = 0
account.1.outbound_proxy.1.retry_counts = 3
account.1.outbound_proxy.1.invite_retry_counts = 3
account.1.outbound_proxy.1.register_on_enable = 1
account.1.outbound_proxy.2.register_on_enable = 1
account.1.outbound_proxy.1.only_signal_with_registered = 1
account.1.outbound_proxy.1.failback_mode = 3
account.1.outbound_proxy.1.failback_timeout = 60
account.1.outbound_proxy_fallback_interval = 60
account.1.outbound_proxy.1.failback_subscribe.enable = 1
account.1.sip_server.1.transport_type = 3
sip.use_out_bound_in_dialog = 0
account.1.outbound_port = 0

Thanks
