Greetings! We have a Cisco UC540 with  Software Release IOS CME CUE CCA 8.0.2 2010-Mar 15.0(1)XA2 8.0 7.1.3 2.2.2 According to the table at another post: I verified that the CUE is 7.1.3 and from the CLI# show config indicates it is running 15.0(1)XA2. The CCA we have been using now hangs on loading the information from the Voicemail.  It will not backup its configuration, and it does the general wacky things that CCA has always done though with even less success since this has happened.   I have tried to do my homework and read up on the possible causes of this.  I am leaning toward the "powered down without shutting down or reloading the system from CCA or CLI" cause and resultant corrupted database?  The UC540 has warned me at some point of a database corruption and I suspect this has now afflicted the Integrated-Service-Engine.   I am an IT novice when it comes to Cisco equipment other than knowing that they are an embedded computer with an operating system that runs as a state machine.  To that end, I am unfamiliar with the CLI.  I know enough to break things and not enough to fix what I have damaged.  I have heard this referred to as a CLI Cowboy.  We have happily used the UC540 system for seven years with little need to interface with it.  We would like to continue using our Cisco equipment however the phone system voicemail has been inoperable for several months, and now calls are not being routed correctly along with the ghost pickup of a ring group that then drops the call.  Needless to say this has impacted our business and I know I am over my technical expertise. The partner we purchased the equipment from we do not do business with anymore and is not an option.  I tried contacting a highly decorated Cisco partner from the website today... (Update: They returned my call and are asking around for someone with UC experience). I explained that I knew our equipment was End-Of-Life (EOL) and out of support however I needed someone familiar with the UC5XX equipment since they are a unique piece of technology our small business invested in. I have done some e-mailing and calling of other support partners in my area.  However, nobody has anyone that is an expert on the UC5XX or they have not supported them for X years and I basically would be paying for them to come up to speed in order to get the system back into working condition.     I am afraid to reset the UC540 system since we do not have the original software load on hand and it will not backup its current configuration.  I know I can copy the terminal screen from #show config out of PuTTY.  Putting it back into the system correctly is another story.  I have customized a few things from CLI years ago since CCA does not give you all the functionality to configure the system (I think this was having to reorganize the softkey buttons on the phones).  The other issue is I remember when the system was installed the ROM files for a few of the 79XX phones we have was not included and had to be manually added in the release of software that our UC540 is loaded with.   I have read up on how to reset the Integrated-Service-Engine 0/0 and earlier today from this link and it gave me the option to try and repair the corrupt database it discovered.   I answered yes to attempt repair, and now the Integrated-Service-Engine is stuck in an endless loop of loading the bootloader, panic, crashing, and rebooting.  I have attached the snippet I collected from the session showing what it is doing at the end of this message .   Again, I don't have the software to perform a clean factory reset if it requires reloading the factory image. Do not know how to make a backup other than from CLI. Am uncomfortable reloading said CLI backup since I watched a few videos of people locking themselves out of the equipment. If I factory reset the system, how do I get the license files reloaded since we do not have copies of it and can't access them from CCA (Plus its EoL so are they even available anymore?) I am trying to avoid investing $X,000's on a new phone system (or a "Pay $XX per handset/mo." that everyone wants to keep pushing on us) My boss is getting upset at losing phone calls from clients and vendors. The office manager is tired of being the "new voicemail" aka a Post-It note pad. To top it all off I have to reconfigure the network and put the UC540 behind another router since the 100MB interface can not handle the new 150MB fiber internet service we updated to.  When the ISP helped me reconfigure the running configuration to change IP address & gateway for the UC540 he accidentally cutoff LAN access and had to get a console cable out to reverse the mistake.  (Plus I do not have a console cable) I feel that if I can get the Voicemail working ( Integrated-Service-Engine ?) and CCA to properly load we will be back to smooth sailing.   I am confused by some of the acronyms, CUE, CUCM, CUCME, ISE, CME, etc. other than I realize they are like individual modules in automobiles which control a specific system: climate controller, engine control module, transmission control module, door control module, infotainment controller (Nav, Sat, CD, iPod, Bluetooth, RSE), etc. With this being said, I am trying to reach out for help/guidance getting from (A) 1/3-functional UC540 to (B) Fully operational UC540.  I am not trying to get assistance for free; just the most cost effective for my company. Thank you for any insight you may have, Rick. ... View more
