Specific DN not receiving calls

Hello everyone. I have started new job and I previously worked as Network and Security administrator. I have studied Voice and here it is my first experiences with Telephony world. Today, i faced one interesting problem. One worker`s phone was working perfectly but suddenly she called and said that she cannot receive calls even from internal numbers but can make calls. I dialed her number and she was right. The problem is last two days no one touched the CUCM. I checked up her phone and DN configurations and everything was okay. Last thing i tried changed her number and now she can get call with new DN. I brought the old DN back and again she cannot get calls. What can be reason for this?

The phone is Cisco 8841

 

Thanks in advance.

Re: Specific DN not receiving calls

Hello,

 

You can try to download and connect to RTMT (Real-Time Monitoring Tool) of CUCM.

You should connect to Voice/Video and select Session Trace Log View and double-click on a call that it doesnt work. 

Let me know if this works for you

What do you see from the logs?

This happened to me before. I just deleted and re-created the extension and it worked but did not had the time to check the logs further.
