I have one presence user that is giving me fits. She can log into CUPC, but she cannot see anyone's status. We can sometimes see her Client Status (although Phone Status and Exchange Free/Busy Status work fine). To further complicate matters, when she tries to generate a Problem Report, she gets a message that there has been an error in CUERT and the problem report cannot be created.
So I did what any red-blood network engineer would do, I sniffed her packets.
On starting up her CUPC, I see the TFTP request of the configuration file and the config file returned from the server. Then I see the client send a SIP REGISTER message, then the server TRYING and OK. Then the server sends a SIP REFER, SIP NOTIFY, and SIP SUBSCRIBE, which get a response from the client of OK (for the NOTIFY), Event Package Not Supported (for the SUBSCRIBE), and Accepted (for the REFER)
So, I assume the key problem here is the client's response of Status: 489 Event Package Not Supported. Does anyone know where this is coming from? I found a reference to two Cisco Bug Toolkit Cases, but those are A) listed as proprietary by Cisco, so unavailable to me, and B) 2 years old.
We are running CUPS 7.0.8.10000-7 and this user is running CUPC 7.0.2.13496. She is also using Windows 7.
