Analog phone connected to
FXS port does not work as
expected. (Continued)
Analog phone is working
with Synapse, but does not
have Deskset capabilities.
Consider the analog phone limitations:
z To make outgoing calls on an analog phone
connected to the FXS port on the ATA, the external
phone number must be preceded by 9 (same as on a
Deskset).
The analog phone connected to the FXS port on the ATA
can pick up incoming calls and make outgoing calls. Idle,
Ringing, Dial, caller ID, and Active states are all supported,
but advanced features such as Call Waiting, Call Forward,
Hold, Transfer, DND, Paging, Park, and Voicemail are not
supported on analog phones.
See “[ATA] Analog Telephone Overview” in the
Synapse Administrator’s Guide at
