I have a couple of questions if I might: I upgraded yesterday to the 17th June release and since then have been suffering from no audio on incoming calls, outbound works fine. Sample of errors if relevant from log: 12:08:57.917 DBPostgressAccessor::addRegistrarContact ERROR: invalid page header in block 131 of relation "prstorage" 12:08:57.897 DBPostgressAccessor::removeRegistrarContact ERROR: invalid page header in block 5 of relation "prstorage" In over a month of prior use I have never encountered these errors and other than the actual upgrade, have not made any other changes of any type. System is being used with vBuzzer as provider and two PAP2's for four analog extensions. All ports identified in this forum has been forwarded from the inception of the original install. No stun server entries, using (I believe) the default(s). My second question pertains to verifying version installed - on the web interface it says "3CX Phone System Version3.0.2328.0" though the upgrade I did should have been to current build. How do I check version? Earliest possible assistance would be appreciated since this system is now my sole method - it was very stable and dependable until now. Thanks. P.S. Can I download and re-install the prior build?
