RE: Multiple OpenVPN connections needed
I am sorry i can't help you in this problem. I think you can ask your distributor for help.
If they can't help you , they will ask the corresponding technical specialist for help.
Please don't remember to share with us if you have figured this out.

Unfortunately, the distributor can't help, could you please pass my question to the Yealink's technical support? This is clearly an error in the phone's firmware. Here is extract from the phone's debug log:

ifconfig -

The IP address 10.8.3.197 belongs to the tun0 interface, it is correctly reflected in the Register message from the Second line and incorrectly placed in the Register message from the First line, here should be 192.168.182.192 address of the esw0 interface!

RE: Multiple OpenVPN connections needed
Sorry. I consult my our engineer about this issue. He said that we don't support this scenario. All phone accounts will connect to VPN network.
