# Asterisk Project : Basic SLA Configuration Example

Added by mdavenport , edited by mdavenport on Aug 31, 2010

This is an example of the most basic SLA setup. It uses the automatic dialplan generation so the configuration is minimal.
sla.conf:

    [line1]
    type=trunk
    device=DAHDI/1
    autocontext=line1

    [line2]
    type=trunk
    device=DAHDI/2
    autocontext=line2

    [station]
    type=station
    trunk=line1
    trunk=line2
    autocontext=sla_stations

    [station1](station)
    device=SIP/station1

    [station2](station)
    device=SIP/station2

    [station3](station)
    device=SIP/station3

With this configuration, the dialplan is generated automatically. The first DAHDI channel should have its context set to "line1" and the second should be set to "line2" in dahdi.conf. In sip.conf, station1, station2, and station3 should all have their context set to "sla_stations".
For reference, here is the automatically generated dialplan for this situation:

    [line1]
    exten => s,1,SLATrunk(line1)

    [line2]
    exten => s,2,SLATrunk(line2)

    [sla_stations]
    exten => station1,1,SLAStation(station1)
    exten => station1_line1,hint,SLA:station1_line1
    exten => station1_line1,1,SLAStation(station1_line1)
    exten => station1_line2,hint,SLA:station1_line2
    exten => station1_line2,1,SLAStation(station1_line2)
    exten => station2,1,SLAStation(station2)
    exten => station2_line1,hint,SLA:station2_line1
    exten => station2_line1,1,SLAStation(station2_line1)
    exten => station2_line2,hint,SLA:station2_line2
    exten => station2_line2,1,SLAStation(station2_line2)
    exten => station3,1,SLAStation(station3)
    exten => station3_line1,hint,SLA:station3_line1
    exten => station3_line1,1,SLAStation(station3_line1)
    exten => station3_line2,hint,SLA:station3_line2
    exten => station3_line2,1,SLAStation(station3_line2)
