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)

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

Background Image


To use a background image with the SPA-942, the image must be :
    • BMP
    • Max : 128 x 48 B/W
    • Recommanded : 95 x 39 B/W
    • 1 Bit Color
Put in in your tftp server then set : tftp://xxx.xxx.xxx.xxx/FILENAME.bmp in "Phone/BMP Picture Download URL"

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 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: (2006/05/11) Even using these instructions does not seem to work. Workaround is to manually set the time offset during daylight savings portion of the year, then switching back. Is anyone else experiencing this issue? - 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

Here is perl script to update personal directory. It takes user names and phones from AD (or LDAP) and places it to phones:

333SNMP?

by geoff.jacobs, Wednesday 04 of July, 2007 [06:44:49 UTC]
I've noticed a lot of vendors list these phones (941+942) as supporting SNMP. Has anyone had any luck finding any documentation on this, or better yet, personal experience in configuring it? I want to add ours to our Zenoss setup, but not getting very far.

333Personal Directory with LDAP

Gijs post has made me get my act together and post a follow up to my original Personal Directory post to include my LDAP integration solution.

333Re: Personal Directory Solution

by gijs.noorlander, Tuesday 26 of June, 2007 [14:39:26 UTC]
With the info Geoff supplied, I created a simple shell-script to update the personal directory in my SPA921 phone from a file.

The script needs a file called tel_list which contains on each line the name and telephonenumber, with a "," as seperation.

e.g.: 
Foo Bar,12345
Foo & Bar,23456

I've placed the script here:
http://got.td-er.nl/SPA921/update_phonebook
and a test-file http://got.td-er.nl/SPA921/tel_list

The script generates an update-script which does the actual updating.
It writes the entries in the tel_list file into the first memory-cells, leaving the rest untouched.
For each wget-operation, (max) 6 cells will be updated and between each update the script sleeps for 10 seconds to give the phone some time to process each update.

N.B. After updating the Personal Directory, the machine can be a little slow when browsing through the list. A reboot will fix that.

Hi Mito,

I am facing the same problem and get busy tone on the second line.
As far as I could read in several other threads Linksys does not support integration with other SIP PABX but their own. Let me know if you'ver found a workaround.
