## Basic SLA

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)
