[mkashifashraf]

Dear All,

I have CISCO2921-CME-SRST/K9 bundle, with ISM-SRE-300 Unity module.

CCME 8.6, CUE 8.6 versions.

I'm facing a problem that outside caller make the call to our network, Auto Attendant receive the call & transfer as per required extension.

Our inside IP Phone is ringing, if no one is there & outside call cut the line(call).

still Inside IP Phone is ringing continuesly, I tried supervisory disconnect but facing the same problem any one have the configuration

of the parameteres of PSTN (STC Saudi Arabia) to configure it properly.

or someone knows any other solution related to this issue??

Please reply soon

If if it doesn't work, you've set the wrong parameters. You should confirm them with recording and a frequency analisys. That is explained in many threads of the same subject.
