An SLA station is a mapping between a virtual station and a real Asterisk device.
Currently, the only channel driver that has all of the features necessary to
support an SLA environment is chan_sip. So, to configure a SIP phone to use
as a station, you must configure sla.conf and sip.conf.
Here are some hints on configuring a SIP phone for use with SLA:
- Add the SIP channel as a [station] in sla.conf.
- Configure the phone in sip.conf. If automatic dialplan configuration was
used by enabling the "autocontext" option in sla.conf, then this entry in
sip.conf should have the same context setting.
- On the phone itself, there are various things that must be configured to
make everything work correctly:
Let's say this phone is called "station1" in sla.conf, and it uses trunks
named "line1" and line2".
- Two line buttons must be configured to subscribe to the state of the
following extensions:
- station1_line1
- station1_line2
- The line appearance buttons should be configured to dial the extensions
that they are subscribed to when they are pressed.
- If you would like the phone to automatically connect to a trunk when it
is taken off hook, then the phone should be automatically configured to
dial "station1" when it is taken off hook.
