CME version and IOS version Compatibility

[Noy-pi]

Hi,

Can someone tell if what is the meaning of "PIA17" in tis Cisco 3925 IOS:

15.2(0.13.4)PIA17

As per Cisco's CME version and IOS version compatibility matrix, it says that CME version 9 must use 15.2(2)T.

http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/requirements/guide/33matrix.htm

Rigth now, my CME version is 9 with IOS version 15.2(0.13.4).

Do I need to change my IOS 15.2(0.13.4)PIA17 to 15.2(2)T ?

What is the meaning of "PIA17" ? in my current IOS mage?

Thanks,

shawn
