• IVR can still be used on an SAS line, but the user needs to follow some simple steps: a) Connect a
phone to the port and make sure the phone is on-hook, b) power on the PHONE ADAPTER and c)
pick up handset and press * * * * to invoke IVR in the usual way. The idea behind this is that if the
PHONE ADAPTER boots up and finds that the SAS line is on-hook, it will not remove battery from the
line so that IVR may be used. But if the PHONE ADAPTER boots up and finds that the SAS line is
off-hook, it will remove battery from the line since no audio session is in progress.
• Set up the Proxy and Subscriber Information for the SAS Line as you normally would with a regular
user account.
• Call Forwarding, Call Screening, Call Blocking, DND, and Caller-ID Delivery features are not
available on an SAS line.
