[cisco-voip] Agents using IP Phone 7841 stuck in reserve state with "busy here" message from SIP phone to CUCM

[Jose Robles]

Yes I am. In fact Cisco gave me an ES sip78xx.10-2-1-12ES3-1 but problem persists. We have two cases open right now for the same Phone model 7841. The other case is for several phones unregistering randomly and won’t register back again until I shut and no shut the switchport. Apparently that IP Phone line is very buggy. Anyone experiencing the unregister issues also?

I hit a lot of issues like that on the 78XX series.  Are you on the latest firmware?

We have a UCCX in 10.5 ver and CUCM 10.5 with IP Phones 7841 for the agents. Their primary line is a personal line and the secondary button in their ICD line is a different partition with number of calls 2, busy trigger 1. Randomly the phones stop receiving calls from the CUCM even though they are in idle state and send a SIP "busy here" message to the CUCM. Since the call does not complete the UCCX sends the call to the same agent as it still is the longest idle in their queue causing the stuck in reserve state in that particular agent. After a cable disconnect to that phone the phone starts receiving calls again. We have a TAC case open but we want to know if someone has experienced this before. Any feedback or help will be appreciated.
