OpenVPN Error with PfSense

[Peleska]

Hi Guys,
I am using PFsense with a Yealink-T38G, Firmware 38.70.150.2.
I Created the Pfsense Side according to the Yealink Documentation, with the Wizard and with sscardefield´s really,really Great Documentation - but nothing works.
I have even reinstalled Pfsense from Scratch....

I have found three things which doesnt´t work if you use the Export Utility
1. You have to unpack and repack the generated client.tar with 7zip on Windows - if you don´t your Phone wouldn´t import the File.
2. If you leave the Line "verify-x509-name PhoneServer name" in the generated vpn.cnf the Phone can´t import the file either.
3. There seems to be a problem with the generated Certificates, the Phone (If you set Phone >Configuration > Log Level to 6 you get a usable Logfile which you can export)
It shows the following Error:
