The documentation gives just enough info to tease me to the fact PBXnSIP can monitor trunks and extensions but does not give enough info to actually set it up. SLA and SCA is the main reason I am very interested in PBXnSIP but I need to test it out to see how well it works.
Basically I want to emulate a Key System (SLA). Additionally, I want to share extensions (SCA).
SLA
I want to set up SLA (Shared Line Appearance) so that all extensions can see the status of all the PSTN lines and can barge in on the lines. If in doubt what I am trying to do just think Key system. If a call comes in on line 1 all extensions have their line 1 light flash. First to answer get's it. That extension should be able to put that call on hold at which point another extension will see the line light flashing and can pick it up. "Joe, your wifes on line 1" for example.
SCA
I want to set up SCA (Shared Call Appearance) which I believe would be several physical extensions sharing the same virtual extension??? This is commonly used by a secretary and her boss sharing the same extension so either/or can pick up the call. Another use is several physical extensions in one department all having the same extension. Not sure what the proper feature equivalent in PBXnSIP would be.
NOTE:
What I am talking about is NOT queues or ring groups or call parking etc. which I am well aware of and have a pretty good idea how to set up in PBXnSIP. They have some similar functionality but are not considered as a replacement for good ole fashioned KSU functionality that my particular small business customers are looking for.
As far as I can tell, this requires configuring Trunk, Account, and the Physical extension a certain way. I really don't know where to start. Any help would be greatly appreciated. An example of a setup like this would be especially appreciated.
I am testing with PBXnSIP on WinXP, Aastra 9133i phones, Xlite, an ITSP account and an FXO gateway. Not sure if Xlite can do this but as long as I can get the Aastra phones working I will be happy.
The production installs will likely have the CS410 appliance for 4 or less PSTN lines.
