  • 4 green/red/orange line keys (cannot be used as BLF)
  • High resolution pixel-based display, larger than SPA-841, (SPA941 has no backlight, SPA942 does)
  • Speakerphone
  • 2.5mm headset jack on all models
  • Styled to look like and feel like a Cisco phone
  • Wireless networking option WBP54G
  • SPA921 is *not* just a 941 without Dual 100mbit Ethernet with POE or backlit LCD.
  • Cisco has stopped development of firmware for SPA-941/921 at 5.1.8, will not get the 5.2 or 6.1 features of BLF




Firmware

( Full support page is here.)

To update the firmware without using the supplied Windows utility, see this page on Sipura products, and follow the instructions under the heading "How do I upgrade...without...Windows?"



Configuration/Utilities

  • Configure the Linksys SPA941 VoIP Phone to Work with Localphone’s VoIP Service
  • Linksys SPA941 Configuration Wizard
  • Linksys SPA Localization Wizard
  • Provisioning
    • Example XML Configuration file Hosted by Sipura THESE DO NOT WORK AND ARE OUTDATED!, You can use the SPC utility to generate a better sample XML file. If you use the XML files from sipura.com the phone will download it but not process it. THE BEST WAY is to update your phone's firmware and then connect to the URL http://YOUR_PHONE_IP_HERE/admin/spacfg.xml and then save that file as your template to get started. Found and verified from this Voxilla Forum Post.
    • Sipura Mass Deployment (Talks about the SPA-841, but concepts are the same)
    • Bulk Provisioning Linksys IP Devices at VOIPSpeak
    • Provisiong tools The SPC utility to generate configfiles. This information is provided because Linksys REFUSE to provide these details to the public and pretty much anyone even VoIP providers will find it near to impossible to obtain "legit"
  • Provisioning the personal directory With a php script (a kind of hack)
  • Ringtone Utility
    • Appears to be designed for the SPA-841, but it correctly detects the SPA-941 & SPA-942 models, and is able to resample WAV files and upload/delete them from the SPA-941/SPA-942.

Use with Asterisk

This phone works well with Asterisk but beware its not likely to support shared lines appearances and other "standard" features now available on other phones. Here is the response I got from Linksys when I asked if the phone will support shared line appearances with Asterisk.

Response (Gordon Green) 05/31/2006 09:13 AM
Dear Valued Sipura Customer, we offer NO support for Asterisk or NO other third party PBX but our own SPA9000 PBX. All of our SPA device have been tested with Asterisk on a global scale and we know are products work, but we don't trouble shoot or offer support when configuring our device to work with Asterisk.


Comment from zalink
For shared lines see http://lists.digium.com/pipermail/asterisk-dev/2005-October/016266.html Many of the other new "features" require SIP-B, and Asterisk does not yet support that. But what features are you looking for? I am very happy with these phones, especialy like their handling of speaker-phone/headset/handset switching with the buttons, and that fact that they can take 2.5mm gaming headsets, which make for excellent quality but way cheaper than the professional headsets.


    • If you have an issue where both asterisk and the SPA94* produces ring tones, set Sticky 183 to YES under EXT1/2

Distinctive Ringtone


To use distinctive ringtone with Asterisk use :

    • exten => xxx,1,SIPAddHeader(Alert-Info:Classic-1)
    • or
    • exten => xxx,1,Set(_ALERT_INFO=n=Classic-1)

Calssic-1 -> standard phone ring cycle
Calssic-2 -> "Short-Long-Short"
Calssic-3 -> "Long-Long"
Calssic-4 -> "Short-Short-Long"

Simple-1 -> standard phone ring cycle
Simple-2 -> "Short-Long-Short"
Simple-3 -> "Long-Long"
Simple-4 -> "Short-Short-Long"
Simple-5 -> Short - "Ringsplash"

Office -> 24 CTU

Where Classic-1 = The name of the ringtone you want. Tested with Asterisk 1.2 and SPA-942 F/W : 4.1.15, 5.1.15a

Bugs, Tweaks, Feature Requests


  • Firmware Version Number
    • MAJOR: (YYYY/MM/DD) Major Bug. A bug which completely prevents the phone from operating in a method that it normally is expected to operate — and particularly if it cannot be reasonably worked around — is MAJOR. Significant protocol violations are MAJOR. - yourname
    • MINOR: (YYYY/MM/DD) Minor Bug. A bug which is an irritation — but clearly is still a bug and not just wanting to see something behave differently — are MINOR bugs. - yourname
    • TWEAK: (YYYY/MM/DD) Tweaks. If you want to see something subtle changed on the device, that would be a TWEAK (e.g., if you have a good reason to move option x from Advanced Settings to Basic Settings). - yourname
    • FEATURE REQUEST: (YYYY/MM/DD) Feature Requests. Use for any new feature request or enhancement to existing features. - yourname
      • NOTE: (YYYY/MM/DD) Use for more information about an entry, or to respond to someone else's entry - yourname

  • TWEAK: (2007/10/30) Some people report problems with voice quality can be resolved modify RTP Packet sizeon Admin Login -> Advanced -> SIP Change: RTP Packet Size: 0.030 to 0.020. - JuanJosePablos
  • Firmware 6.1.3a 9/30/2008 (for 942) : anyone tried this one on SPA 941 ? it has some nice features : ldap, BLF, and more...
    • As of 2010/02/15 the latest code from Cisco for the 941/921 is 5.1.8. - dean.l
  • Firmware 4.1.18 (available only from Linksys web site. Sipura site now appears to be depreciated)
    • MAJOR: (2006/11/27) Major Bug. SPA-942 & 941 Group Paging puts calls on hold. If you are in a phone call and someone pages all phone or intercoms with your phone, your existing call is put on hold without warning and stays on hold unless you manually select the line button. This makes paging/intercom pretty much useless on these phones. Solution is to use this work around. FIXED: as of firmware 5.1.15(a). Phone now does not put the call on hold and instead mixes the page audio and the in-call audio. Note: not available for the 941 yet.
    • FEATURE REQUEST: (2008/01/21) Feature Requests. Ability to remap the soft keys, as having to right-arrow during a call to find the bxfer is confusing my userbase, especially when there are blanks in the softkeys due to features I've turned off. - andyb2000

  • Firmware 4.1.15
    • MAJOR: (2006/08/22) Major Bug. SPA-942 & 941 Group Paging puts calls on hold. If you are in a phone call and someone pages all phone or intercoms with your phone, your existing call is put on hold without warning and stays on hold unless you manually select the line button. This makes paging/intercom pretty much usless on these phones. Linksys support claims "this is a feature, not a bug."
    • MINOR: (2006/09/18) Minor Bug. SPA-942's LCD backlight illuminates when a NOTIFY (message-summary) is received. Originally reported by juice for 4.1.12a also applies to 4.1.15. - cortez

  • Firmware 4.1.12a
    • MINOR: (2006/06/09) Minor Bug. SPA-942's LCD backlight illuminates when a NOTIFY (message-summary) is received. - juice
    • MINOR: (2006/05/11) Minor Bug. Daylight savings function not working - Altair256
      • NOTE: (2006/07/12) DST adjustment started working for me after I set a valid Primary NTP server (north-america.pool.ntp.org). - psndcsrv
    • FEATURE REQUEST: (2006/05/18) Feature Requests. Implement remote storage of the Personal Directory. Basically, make it so the phone optionally attempts to download an XML file just like the provisioing aspect of the phone. - Altair256

Notes
