Per Brians request here is a summary of what I hope to accomplish with SLA/BLA and FS

What I hope to accomplish with freeswitch is a SLA/BLA scenario.

I want extension 1000 on line1 on all phones registered with the system

I want extension 1001 on line2 on all phones

I want extension 1002 on line3 on all phones.

Inbound call:

enters system, dials extension 1000, line1 rings on all phones, a phone picks up line1 and the status on all other phones shows as inuse for line1.

Outbound call:

User hits line selection of their choice (1, 2 or 3) and dials an outside number. The status of the line he is using would be shown as active across all phones.

Misc:

Call should be able to be put on hold on one phone and picked up on another

phone using the same line button.

Thoughts:??

Maybe conference can be used so two phones can share a conversation with an inbound or outbound call?
