Hi Zhang,

Could be related to Toll Fraud Preventtion since the IOS would have been also changed to 15.x

Just read the DOC and check by running debug voip ccapi inout for any blocking.

http://www.cisco.com/c/en/us/support/docs/voice/call-routing-dial-plans/112083-tollfraud-ios.html

you can use the nelow command to disable toll fraud.

voice service voip
no ip address trusted authenticate

regds,

aman
