First Impression Video Review of #Polycom #Spectralink 8400 Lync Features

 

Note: The Polycom 4.0.1 UC Firmware is NOT Microsoft Lync Qualified as of 2/23/2012.
Note: Lync Limitations of Polycom 4.0.1 FW: Click Here (Slide 11)
Note: This is first impression thoughts, I’ve only used the device several days.

The Polycom Spectralink 8440 is a SIP, WIFI based portable phone that Polycom has released a firmware update that brings Lync connectivity to the device.

This was my first experience with Polycom’s non-Lync Optimized devices and it took me just a little bit to orient myself (which I plan to blog on) but after figuring out the basics, upgrading to 4.0.1 and configuring the device to register with Lync (following Jeff Schertz’ blog post) worked with no surprises.

My first impression of the Polycom device (Lync aside) is that the screen resolution and unit build quality is very good. The user interface is intuitive and you can do common call features in just a few clicks.

Well, below is the video:

Ubiquitous VoIP UC over Mobile Data Plans: A Myth? Very Few Enterprise Vendors Seem Willing to Commit


can voip ride on the mobile data plan pipe

I’ve been trying to find a major UC Vendor that supports UC media (voice/video) over mobile data plans (2G/3G/4G, etc). While there is a lot of marketing that makes it appear that UC Voice/Video/Collaboration on VoIP is a smooth ubiquitous experience, when you read the technical details, the solution is really designed to work on “WIFI” or “your corporate” network. In some cases, it is noted, you need to switch to your mobile voice network when you leave corporate WIFI.

As an example of this reluctance read these excerpts found in Jabber for Android release notes:

  • “Voice quality over public Wi-Fi and mobile data network connections cannot be guaranteed.”
  • “When using Cisco Jabber to participate in Cisco WebEx conferences, you may experience audio issues. For example, you cannot hear participants, participants cannot hear you, you hear choppy or synthetic audio, or participants hear your audio as choppy or synthetic. To resolve these issues, tap Hold and then tap Resume.”
  • “Voice quality over mobile data network varies depending on the quality of your mobile data network connection and cannot be guaranteed. Examples of voice quality issues you may experience when using a mobile data network include the following:
    • If you are driving and listening to a voicemail message, you may have problems hearing the entire message and the audio may sound choppy or synthetic.
    • If you are driving and replying to a voicemail message, the recipient may have problems hearing the entire message and your message may sound choppy or synthetic.
    • If you try to access your voicemail and you enter your PIN, the time delay associated with remote access may cause prompts to play out of sync, or you may hear a message that you did not enter the PIN on time.”

Below is my informal (I did not contact each vendor/don’t claim to be expert in their mobility products) compilation of vendors that at first blush appear to do UC over VoIP everywhere, but when you start reading the technical brochures in it appears they are committing only to WIFI and Outside Voice/ Call Back/ Mobile Voice Network when not in WIFI range.

Note: I should note that vendor reluctance to commit to VoIP over mobile data networks is not a reflection against UC vendors, but a sign that mobile data networks in some (many?) areas are not primetime ready to handle real time communication data.

Note: If you find any mistakes in my informal research or have a vendor that does commit to VoIP over mobile data plan, let me know, along with URL source, and I’ll update this blog. Also if there is another vendor to add, drop me a comment.

Shoretel Mobility: Wi-Fi/Mobile Data Networks

Shoretel Mobility can work over WIFI or Mobile Data Networks. In their technical notes (sources below) they note that when on WIFI you should use the below vendors, and i quote the list:

      • Cisco (including integration with Wireless LAN Controllers and Mobility Services Engine)
      • Aruba (including integrationwith Wireless LANControllers/Switches)
      • Meru
      • Motorola
      • HP
      • Trapeze
      • Aerohive

When on 3G or less I wonder what the plan is to keep from an “experimental” end user experience?

Locktec WP04 Review - Is a Cheap, SIP Wifi Phone Worth Your Look?



I keep seeing these cheap SIP WIFI phones showing up on the radar and thought I'd take a look at one and see if, just perhaps, you don't always get what you pay for!

I've been seeing the Locktec WP04 here and there (ebay, youtube, yippz.com) and thought I would get one to try it out. Will a $129 WIFI SIP phone work as a low cost, business grade, portable phone? It appears that the WP04 is branded by whoever sells them in your locale and Yippz.com is providing them to the USA branded as the Locktec WP04. (Search on ebay and you will see other branding. Such as yongsongyan)



The Yippz.com name doesn't particularly evoke enterprise grade quality or confidence so I'll admit I somewhat expected to be dissappointed but I thought I'll forge ahead. I contacted yippz.com sales support to see if they would send me a courtesy unit to review but they kindly said they don't do that and since they have a restocking fee they couldn't recommend that either. So, I laid out the $129 and financed this whole thing entire on my dime. I would like to note that yippz.com service responded in a very timely fashion.

The unit was shipped via USPS and came in a timely fashion. The package includes power plug, USB cord, battery, and the WP04 all inside a nice box. I immediately found that the unit looked nicer that I expected: piano black and decent "first glance" fit and finish. There was no "Locktec" or "wifi" branding on the unit I recieved (which is probably a plus as far as good looks go?) The unit does feel very light, even with the battery in. (a little weight inside might make it feel more balanced?)

Registering to WIFI and to our SIP based phone system was very easy and straightforward. (well, as easy as typing a complex password on a phone keyboard can be! ;-) But, once again, NO trouble configuring it. When I went to make the first call it just disconnected the call with no warning and the pbx showed it was still connected. Hmm...tried another call and the unit powered off. I checked and the unit had 3 bars of battery. hmm. After emailing to yippz.com support (once again, excellent response time...very good) they brought my attention to the fact that I need to charge the unit for 10 hrs on first several charges. Okay! got it. So I plugged it in and the next day I was eager to try it out...But it was froze! When I pulled the battery and restarted the unit is still only had 3 bars! So, I decide I would plow ahead and try it's features anyway.

I could make calls today. But I noticed a buzz during the first 3 rings. No big problem. After using the phone I soon noticed that there was no "Hold" button. Am I missing something? No, yippz.com support says that this phone handles 1 call only. Okay, fair enough. I soon noticed there is also no "Transfer" button. And since there is no hold button I can't use the star keys on the pbx to do a transfer that way either--so truly, no transfer. I accept. But then another thing kept happening to me: I would press "End" to end a call and the end button would get stuck under the sourrounding case. Ouch. Another odd issue I noticed is that if I call the unit and the remote party hangs up the WP04 will keep ringing. (this could be a pbx interop issue I guess) There is also no message waiting indicator. The WP04 also does not have applications like Calendar, Calc, etc often found on mobile devices.


When I talked to the yippz CSR about the lack of business features they noted:

"The WP04 is a basic wifi voip phone with very few bells and whistles. We sell them mainly to large companies for extension use and 2-way radio style comms"
I think that is a fair and honest assesment of this unit.

Now for the features: The unit does have a speaker phone. Also you can save 4 SIP profiles setup. (but the unit can handle only one call at a time.) The unit does have a phone book and will notify you of missed calls.

Check out my video review of the Locktec WP04 below:



The Good:
-piano black
-very light,
-looks nicer than expected
-good support response--1 hr

The Bad:
-one call at a time
-no transfer button
-no hold button
-no message waiting indicator
-no Missed Call Idicator
-audio stuttered for me when pressing buttons at times? (to put on mute)
-no web interface for configuration
-"end" tends to get stuck in the down position
-My first charging experience: overnight--not charged, & froze, buttons don't response

Summary:
It's a cheapy alright. Not a serious business unit--wouldn't recommend to a business. I would say from my initial experience that this will not be a phone you can just "set and forget". It's low cost (from some vendors as low as $69) but I guess the old adadge is true: you get what you pay for.
