I have a used UC520-16 unit that I'm trying to setup I have some CP 524 G phones and when I pluged them in they keep intiating, but never finish.

Also I have a Lynksys SPA 942 phone that finish intiating, but it doesn't have dial tone.

Aren't phones suppose to work right out of the box on the UC520, at least have dial tone?

Hi Jaime,

A UC-5XX may or may not work right out of the box, in most cases i just use CCA and reset them to a factory default state, and it is a good idea to use the latest software pack to do this. Then quickly run through the telephony wizard and at least give it a basic provisioning.

If your system is in a factory default state then auto reg should be enabled, meaning that when you plug a phone into the system it will be auto allocated an extension. However an SPA942 will not, this is not a phone designed for the UC5XX series appliances, it is a SIP based device that would require special programming on the system in order for it to work.

Do you have CCA 2.2.4?

Do you have the latest UC-5XX software pack?

thanks David. I do have CCA 2.2,

but I don't have the latest software pack. I will download it and let you know.

How did you do?  The uc500 software pack has the phone loads in it, and when you use CCA to perform the SW upgrade the Phone Load Manager (PLM) will pop up and ask you which phone loads you want on your system.  Just keep in mind a uc 520 first have the flash space to fit them all,, so please just select the ones you need.  UC 540 or UC 560 don't have this worry.  PLM can also be launched separately if you need to adjust.    And we don't support the Spa9xx as Dave replied on this system.  Look at the new SPA5xx series going forward as the CP5xx announced EOL plan.

I reseted the unit to Factory default downloaded the latest sof

tware pack. When installing the software pack with CCA is gets stock at

Analysing phone loads in software pack. it goes all the way to 99% and goes back to 97%

and it keeps doing it.

any Ideas.

So it never got to the point where it asked you to select phones?

What is the 'dir flash:' look like please?

CCA only supports directory file structure.

Please reset to factory defaults and check the box that says AUTO DISK CLEANUP.

under restart/reset I don't see an option for auto disk cleanup.

the auto disk cleanup is under  software upgrade.

are you refering to the option Apply default configuration under software upgrade?

SW Upgrade is where it is.

Can you do an upgrade to the same bundle zip and have that box checked.  Select Yes to overwrite IOS if its the same.  SHould take 3 minutes. then reload.

If you check that box, it should work.

I'm having the same problem. it keeps getting stock at analyzing phone loads in software pack.

and if I try to do a factory resete under the restart/reset it tells me that I must update the software pack first.

Golly Jeepers.  So sorry about this.

We started supporting directory formated flash around CCA 1.9 time frame.   I noticed the original post shared flash has a very old IOS image (like XW4), so that explains why UC500 flash is flat.

So I need to find out what happens first...PLM or formatting of flash, and if PLM goes first and doesnt like flash format (lack of phones subdirectory), what do we do.  I may need your log (CCA Help-> Support-> Troubleshooting Log: Generate)

Its clear Reset doesnt have such the option.

But I am asking in parallel to see if this is a known issue and if we have a way around it.

I see alot of errors in the application log.  I forwarded it to Engineering.

In the mean time, since it is not recommended to build on XW4, and I assume this is not a field deployed system, may I ask if you have tried to factory reset from the SW Upgrade GUI.  In other words, Check BOTH Factory RESET and Auto Flash format box and do an upgrad?.

Also, can I ask you if your PC is on the local LAN or are you using CCA over a VPN connection?

  (local is recommended for this).

From the SW upgrade GUI my only options to check are auto disk cleanup and apply default configuration.

I also select all under software. I;m using CCA version 2.2 (4)

I have only  the factory reset option under restart/reset, and it forces me to do a software update before I'm able to do a factory reset.

I'm conected directly to one one the the ports of the UC520.

yeah,  apply default is factory reset.   Please try upgrade with that and auto format flash.

Click the black circled button (BEFORE) you browse to the SW pack is what I am saying....

This is exactly what I did last time and it just hangs between 97 and 99%

OK, at this point I think its time to open a case with TAC.  I tried :-)

There is one last thing you can try, and that is remove some really big phone loads from flash.

(you didnt provide the very bottom of the dir flash:, which shows space remaining, but I suspect you dont have enough space and this could be causing the issue)

Removing these loads wont impact existing phones, since they already have their loads (old at that as well).

If this is a production system, dont try this, just call TAC.  But if you can be comfortable about causing an outage, then you can try this.

Basically delete those very big phone loads from flash so you have at least 20% flash free and then try CCA again.

Hi Jaime,

If you are willing to take things to the next level (TAC as Steve has pointed out). If you are not quite prepared to take it to that level just yet you can do one of the following.

  • Remove the CF card from the system and use a card reader on your computer to access it, this way you can remove and re-organize the file on the card with ease, however note that creating a directory on the CF card in a windows environment will result in the folder name being in upper case when inserted back into the UC, avoid creating directories in the windows environment and do it on the UC itself.
  • Delete the current IOS residing on the card and put on the new one from the software pack, also use the factory default .CFG file that is appropriate for your system and put that on the CF card and then apply it to the system ("ROUTER# copy start" this will default the system, but do not write mem after doing it), you will need to reload to apply the new IOS and to also apply the default config.
  • Delete all Phone loads not in use, taking up room on the card is a wasted excercise and will result in vairable failures

Keep in mind the above are not supported methods by Cisco, I can get away with providing you instructions on doing the above, but it is highly unlikely the Cisco reps on here will, you also might not get support on here for doing so, however TAC might even ask you to do the above, but this is then supported by them and is under their instructions.

Do the above at your own risk and only if you are confident to carry it out, if you have any hesitations what so ever then stop and take your issues to TAC immediately, avoid putting yourself in a world of hurt.

Hope you get the system to the state you are wanting it in, and you begin enjoying its fruits.
