I migrated the version 3.0 to last version on web. The test was do offline to preserve the working 3CX. Is my intention add a new PSTN.... but the page give me a timeout. I've restarted EVERY Windows services: the page give timeout. I've restarted the PC (same result) I've tryed to access all other configuration pages (all working well) Finally, I reconnect internet and the page appears. Is correct?
