Digium Phones: DPMA 3.2.2 and Phone Firmware

By Malcolm Davenport

IP phones DigiumAloha! Today marks the release of new versions of both DPMA and Digium Phone Firmware. Both are available now by following the links on the DPMA Installation wiki page.

We have a number of great new features for Digium phone users, administrators, and service providers, as well as a few bug-fixes.

For users of Digium D65 phones, we’re pleased to provide a new feature allowing you to always see your most important people. Previously, scrolling to one of your many Rapid Dial pages via the pagination keys would leave you on that page indefinitely. The D65 now has a handy timeout feature to automatically take you back to the first page,  where your most important people reside.


Expanded language and tone support:

For all D6x model phones, including the D60, D62 and D65, we’ve added Russian language and tone support – Здравствуйте!. This is only possible with the D6x model phones because of their high resolution displays and enables Russian-speaking users of Digium phones to use them more effectively. Спасибо!

And, for all models of phone, for any users in the South Pacific that might prefer it, New Zealand tone support has been added!

New capabilities for phone administrators:

For Admins, for all models of phones, we’ve improved PIN entry in all areas. Before, as you entered PIN codes, someone could stand over your shoulder and see the keypresses represented on the screen. Now, passwords for Admin Settings, Global Config and Phone Config PIN codes are all hidden as they’re entered, making things a little safer for admins everywhere.

Also for Admins, for all models of phones, we’ve added improved remote restart capability. Previously, phones could only be restarted by unencrypted SIP message. Now, phones can be restarted directly from the Web UI or a remote, authenticated web call to the phone. If an admin gets into trouble, having better remote restart capability can be a life saver.

For all models of phones, we’ve also improved the LLDP neighbor advertisement. For Admins that use monitoring software to see the LLDP neighbors attached to a switch, one used to see a bevy of the same thing. Now, each phone reports its model and its MAC in its SysName, so your reporting software looks much more pleasant and manageable.

We’ve also done two Admin-focused additions to D40, D45, D50 and D70 model phones that were previously only available in the D6x models of phones. First, we’ve brought back the feature that enables phones to indefinitely retry DPMA server contact in the event that the server’s unresponsive – no more manual Retry softkey on the phone. This is important in situations where the phone boots up before the server…such as a horrible campus-wide power outage.

The second feature we brought back is the rest of the 802.1X support. Previously, D40, D45, D50 and D70 model phones were only capable of EAP-MD5 authentication. Now, they’ve got the full gamut of support provided by the D6x phones, including EAP-PEAPv0/MSCHAPv2, EAP-TLS, EAP-PEAPv0/GTC, EAP-TTLS/MSCHAPv2, EAP-TTLS/GTC and EAP-MD5.

We’ve even got a new feature for Service Providers, for all models of phones. Previously, phones provisioned to non-DPMA systems would divulge the full cURL path, including user and pass, on boot, from which the configuration was being retrieved. Enterprising users could jot a quick note and then go perform their own retrieval of the config file. That’s not desirable. Now, phones can disguise the location from which they’re retrieving the configuration and will hide the username and password credentials so they can’t be retrieved directly by the user.

For the D65 model phone, we’re pleased to say that we are now officially Bluetooth approved. You’ll notice the old, placeholder icons on the phone have been replaced with the standard Bluetooth wireless icons.

Bug fixes:

Maybe bug fixes are more to your interest? We’ve got a list of fixes available on the Firmware change notes wiki page.

Aside of the new features and bug fixes, the most significant change is in the phone’s codecs offering. When we introduced support for the Opus, G.722.1 and G.722.1C licensed by Polycom©, and iLBC codecs, we overcooked things a bit with respect to the MTU size of the phone’s INVITE packets. To address this, we’ve reversed course and disabled these codecs (along with Linear 16 8kHz and 16kHz) by default. This means you’ll have to explicitly turn them on to use them. To do so, you’ll have to either be configuring your phones directly via XML, the web UI (we don’t recommend this method), or in DPMA 3.2.2. DPMA 3.2.2 provides new codecs control over the phones.

So go, have fun, enjoy, and bring us your feedback. Thank you for using Digium’s phone products.
