I'm not seeing any available firmware updates on my uc320. Is there anything I have to do to enable the display of the RC firmware on the uc320's device status page?

If not, are these available for download so I can perform the update via the PC.

Hi Jamie,

Please make sure that you have connectivity to the Internet as this is hosted in the Cloud.  Also, make sure you have the PMF file installed on your UC320W.  WAN connectivity is required on the UC320W to do the Cloud based upgrade.  There is an option to download the firmware to your PC from the Cloud.

To download the intermediate release 2.0.12, you may use this link to 2.0.12 download.  We won't be posting Release Candidate firmware to CCO.

Just to let others know. After I installed the rc pmf correctly I was able to successfully upgrade to the latest RC without issue. It did the 2 stage update for me with no hassles.

Thanks again Christopher

Hi Chris,

I am using version 2.0.13(2) because of the DTMF in AA. When I try upgrading to the 2.1.0 RC, it fails. Should I revert back to and then install this PMF and then try to upgrade to latest RC ?



Christopher Edg... Mon, 08/22/2011 - 09:35

Hi Azher,

Did you follow the instructions in the release notes to upgrade to 2.0.12 (Link to manually download 2.0.12 is found 2 posts above) first?  There is also a know issue that if your UC320W has a slow WAN connection the upgrade may fail.  The workaround is to download the firmware to your PC first then perform the Upgrade from your PC ( Status -> Devices -> Upgrade from PC).

If you are still having problems upgrading, please post a screen shot of exactly where it fails and the steps you took to upgrade.

If i understand correctly, then I will have to downgrade to then upgrade to 2.0.12 and then upgrade to RC



Christopher Edg... Tue, 08/23/2011 - 06:47

Hi Azher,

No need to downgrade to 2.0.9(3).  Go to 2.0.12 which is a special upgrade firmware, then go to 2.1.0 firmware.


azher.amin Sun, 08/28/2011 - 15:45

Hi Chris,

Upgrade process went fine.

However as I posted in another thread, Voice delay calling from one phone to other is still there. I noted someone else is complaining about it.

Interestingly, if I enable intercom and call someone via intercom there is no voice delay at all and its perfect.

Can you please let me know why this is happening ?? This is all LAN environment.



Christopher Edg... Mon, 08/29/2011 - 06:55

Hi Azher,

The engineering team is analyzing the logs collected on a similar case that came into the SBSC.



azher.amin Mon, 08/29/2011 - 09:10

Hi Chris,

It was really frustrating talking with the client yesterday, Please let me know if I you need logs from my side as well.

I need this to be addressed as soon as possible.



azher.amin Wed, 08/31/2011 - 17:14

Hi Chris,

Can you please tell if engineering team found issues with the voice delay during regular calls ? And I am wondering why there is no delay for the interom calls. Some explanation would be appreciated.

Hi Christopher,

Is there any likelihood that the dialling plan will get an update?

We are suffering with the fact that we are on BT Feature lines which require you to dial a 9 when making external calls. So with the UC320 requirement to dial 9 we currently have to dial 99 to get an outside number.

Best regards,


Alberto Montilla Thu, 08/25/2011 - 08:58

Hi Tim;

Quick question. What exact change are you looking for on the dial plan (trying to understand better the request)?


trustedit Thu, 08/25/2011 - 10:01

Hi Alberto,

Thanks for the reply

Well we have two PSTN lines supplied by British Telecom, the lines are called Featurelines and they allow you to have some basic PBX functionality, these are pretty common type of line in the UK.

The problem is with these line you have to dial 9 to make an outgoing call. Now that we have installed the UC320 using both these line we have to dial 9 to select an outside line (for the UC320) and then another 9 for the BT line.

So we would end up dialling “99>External Number” instead of just “9>External Number”.

Now here comes the real problem. Up until today we have just dialled two nines and then our outgoing number and this has worked but as of the latest 2.10 (22) firmware it will not allow any outgoing call due to the dial plans Because of course the second 9 is adding another number to the dial number.

So we really need the option to be able to tell the UC it needs to add a preceding 9 when dialling down an FX0 line. I am not sure where this would be in the configuration but I would have expected it on the FX0 line configuration screen.

Best regards,


Alberto Montilla Mon, 08/29/2011 - 09:10

Hi Tim;

Fully understand now. Can you open a case with the SBSC to have a tracking number. Meanwhile I will directly escalate to engineering for a solution. This may require small changes to the platorm low level configuration.


chrkaise Fri, 08/26/2011 - 13:01

This is great, capacity changes and bug fixes! I upgraded my lab 320 last night to this and no issues so far. Using a SIP line from and SPA525G's, so those went through the upgrade process as well... surprisingly fast and steamlined upgrade process

Thanks Chris!

You should be able to use a "Centrex" line on a Shared FXO. With Shared FXOs you are picking up the line right away.

In the PBX mode the dial plan is not expecting another 9.


trustedit Mon, 09/05/2011 - 02:47

Hi Navin,

A Shared FXO is no good to us.  As per Alberto's instructions I have now created a support ticket with SBSC.
