SPA509G Firmware 7.4.9a Upgrade Broke Distinctive Ring
I just upgraded two of the SPA509G phones on our system to formware version 7.4.9a. Now it seems that the phones are no longer honoring the Alert-Info SIP header and defaulting to the Classic-1 ring tone. This caused a minor revolt in the office so I tried backing the phones back to 7.4.7 and the phones no longer registered with the Asterisk server. I've been able to manually set the Simple-1 ring tone on the two phones, but the distinctive ring patterns that differentiate between internal and external calls isn't working since the phones seem to ignore the Alert-Info header. I'd sure appreciate some help resolving this before I get lynched.
Is it possible to successfully back the phones back down to the 7.4.7 firmware?
I've watched the network traffic with an analyzer and I can see that the Alert-Info header is being sent and the phones that weren't upgraded to 7.4.9 are still accepting the Alert-Info header and ringing as desired. I am using asterisk v184.108.40.206. Here is an exerpt from the dial plan that has been working until the firmware upgrade.

Thank you for the reply.
I was able to obtain the older, 7.4.7 firmware, but when I applied the 7.4.7 firmware to the phone it stopped registering to the Asterisk server. I even tried doing a factory reset and re-applying the 7.4.7 firmware without success. Unless I can find a way to successfully downgrade the firmware it looks like I'm out of luck until the new firmware is released. I'll keep my fingers crossed that the new firmware fixes this.
