I have upgraded a v2 cab from 8.1 to 9 prior to essential edition licence.

Licence now in, system can see that it is a valid licence but system status & phones say that there is no valid licence.

This is not a R9 upgrade licence.

Will downgrading to R8.1 help getting this system running? or is there a fix?

Not sure I understand your question, but I'll take a stab.
You will need a lic to upgrade from 8.x to 9.x.

4 Technical Notes
4.1 Upgrading IP Office core software
When upgrading to Release 8.1 from a previous major release an upgrade licence is
required. It is recommended that the IP Office Release 8.1 Software Upgrade license is
installed before upgrading the system. Although the license key may not be recognized
immediately by the system running an earlier major release of software, it will be
recognized when the system is upgraded to Release 8.1.
Note: An IP Office 8.0 system with Essential Edition functioning but not enabled with the
required Essential Edition license key will have all telephony functionality disabled after
the 8.1 upgrade. It is important to verify the license information prior to upgrading. If
Essential Edition is not visible in the license summary, an Essential Edition license must
be purchased and installed prior to attempting the 8.1 upgrade.
