SPA504G needs no activation to work. It just needs to be configured. Its about step 4 of your recipe. You ordered the phone to fetch configuration from https://lscfg.8x8.com/linksys/custom.cfg and https://lscfg.8x8.com/linksys/$MA.cfg
The critical question is - did phone fetched the configuration as requested ?
It's up to you to verify - just read phone's configuration. Is it configured for 8x8 service ?
If not, why (check phone's syslog and debug messages) ?
If the phone is properly configured, we can continue.
Configured phone will REGISTER to designated SIP proxy. Check line status. Is registered ? If not, why (check phone's syslog and debug messages) ?
If phone is registered correctly, we can continue.
Pick up the handset. Based on your description I assume the phone has been configured to dial a IVR phone automatically. Despite you didn't dialed number manually, it's still just standard SIP call. Did the call setup completed successfully ? If not, why (check phone's syslog and debug messages, also check SIP packets to observe proxy's response).
If phone can call successfully,the phone configuration is done and working.
Now you can use IVR to activate 8x8 service. This step have nothing to do with phone - it's activation of VoIP provider service unrelated to phone. Is the activation successful ? If not, why (ask service provider for reason) ?
If yes, activation is done.
OK - so back to your original question. I'm unsure you are waiting a hour for activation. May be you are waiting for configuration. Or for registration. Unless you identify what the phone is waiting for, we can't identify the cause and advise further steps.
