[Asterisk-Users] Linksys SPA-941 multiple line appearences

[Michael Keyes]

Has anyone had any experience with the Linksys SPA-941 when it comes to 
multiple line appearences?

The 941 comes with 4 line appearence buttons which can individualy be 
configured to point at any extension.  The phone is capable of 2 extensions 
out of the box with the option to add  2 more for a license fee.

The 941 manual states that, "The Call Waiting function is activated when a 
device has a call in the active state and another call is incoming. The 
phones in the SPA series do not support multiple calls on the same Line Key. 
Incoming calls are assigned to an unused Line Key, causing the Line Key to 
quickly blink red. (Note that the Voice Mail Waiting Indicator also blinks 
red whenever there is an incoming call.) The phone will not ring. However, 
to alert the user, the call waiting tone is played into the active audio 
device."

During testing I set up an Asterisk 1.2 box with a 941 phone using firmware 
ver. 4.1.8.  I configured 1 extension and set all 4 line appearence buttons 
to point to that extension.  If there was an active call in progress I could 
place that call on hold and by pressing line appearence button 2 was able to 
place an outgoing call.  That outgoing call would appear to come from 
extension 1.  This is all working as desired.

If an active call was in progress and someone called my extension the 
product manual indicates that call should appear on line appearence button 
2.  During my testing Asterisk would flag my extension 1 as busy and instead 
of ringing the phone on line appearence 2 would send the call to voicemail.

Is anyone aware of any configuration setting needed on either the Asterisk 
server or on the phone to make Call Waiting function as described in the 
manual?  Thank you.
