Does This Guide Describe How To Operate My IP Phone?
IP Phone operation - for example, how to use the buttons, softkeys, and hard keys
on your model IP phone - is beyond the scope of this guide.
For instructions on operating Aastra IP phones, and using Aastra IP phone
features, refer to the AastraLink Pro 160 IP Phone User’s Guide.
How Does Auto-Fax Work on the AastraLink Pro 160?
The AastraLink Pro 160 allows you to physically connect a FAX machine to FXS
Port A on the rear panel to send/receive fascimile communications. When two Fax
machines (or Fax modems or Fax servers) first connect, they exchange tones
called the called station identification (CED) and calling tone (CNG). These tones
confirm that the other party is a fax machine and not a voice call.
A calling fax machine plays the CNG tone, a short 1100Hz tone that is
periodically repeated. An answering fax machine plays the CED tone, a
high-pitched (2100Hz) long tone.
The FXS Port that the FAX machine is connected to on on the AastraLink Pro,
detects the incoming V.21 fax answer tone and CED calling tone in parallel for all
FXO calls. If a fax call is detected, it routes through to FXS Port A. If FXS Port A
is busy, the call gets a post-answer busy tone, so the calling party can try again
later.
For more information about Auto-Fax, see Chapter 3, the section, “
Does the AastraLink Pro Support Routing to a FAX over IP (FOIP)
Device?
No. The AastraLink Pro is limited only to the FXS ports on the back of the
AastraLink Pro. Voiceband fax over IP is also not supported by the current
software.
