3. In the Port field, type the port address.
4. In the Name field, type a name to associate with this fax.
5. Move to the Data Restriction field and type y.
Entering y in this field prevents calls to and from this extension from being interrupted by
tone signals. This is important for fax machines and modems as these signals can disrupt
transmissions of data.
6. In the Distinctive Audible Alert field, type n.
This eliminates the distinct 2-burst ring for external calls, which often interferes with the
auto-answer function on fax machines or modems.
7. Press Enter to save your changes.
Enabling transmission over IP networks for modem, TTY, and fax
calls
Prerequisites
The ability to transmit fax, modem, and TTY calls over IP trunks or LANs and WANs assumes
that the endpoints sending and receiving the calls are connected to a private network that uses
H.323 trunking or LAN connections between gateways and/or port networks. This type of
transmission also assumes that calls can either be passed over the public network using
ISDN-PRI trunks or passed over an H.323 private network to Communication Manager switches
that are similarly enabled.
As a result, it is assumed that you have assigned, or will assign, to the network gateways the IP
codec you define in this procedure. For our example, the network region 1 will be assigned
codec set 1, which you are enabling to handle fax, modem, and TTY calls.
To enable transmission over IP networks for modem, TTY, and fax calls:
8. Type change ip-codec-set 1 and press Enter.
The IP Codec Set screen appears.
Complete the fields as required for each media type you want to enable, and press Enter.
For more information on modem/fax/TTY over IP, see Administration for Network Connectivity
