34.2.1 Configuring Rerouting of Calls to Fax Destinations

You can configure the device to reroute incoming SBC calls identified as fax calls to a new
IP destination. The device identifies a fax call if it detects, within a user-defined interval, a
calling (CNG) tone on the originator side (incoming IP leg). If the device detects a fax call, it
terminates the call and reroutes it using a new INVITE to the new fax destination (new IP
Group). If the initial INVITE that was used to establish the voice call was already sent, the

value. For example, if the Dial Plan rule is configured with tags
"Country=England;City=London;Essex", the default tag is
"Essex".
For more information, see Using Dial Plan Tags for Routing
Destinations on page page 761.
Note:

The parameter is applicable only if the 'Destination Type'
parameter is configured to Destination Tag (see above).

Only one tag can be configured for the parameter.

Only the tag name must be configured (not the value, if
exists). For example, if the tag is configured in the Dial Plan
rule as "Country=England", configure the parameter to
"Country" only.
Defines a SIP response code (e.g., 200 OK) or a redirection
response (with an optional Contact field indicating to where the
sender must re-send the message) that the device sends to the
sender of the incoming SIP dialog (instead of sending the call to
another destination). The parameter is applicable only when the
'Destination Type' parameter in this table is configured to Internal
(see above).
The valid value syntax is (case-insensitive):

For SIP response codes:
Reply(response='<code>')
The following example sends a SIP 200:
Reply(response='200')

For redirection responses:
Redirect (response='<code>',
contact='sip:'+....)
Redirect (contact='...', response = '<code>')
Redirect (contact = 'sip:user@host')
Examples:

The device responds to the dialog with a SIP 300 redirect
response that includes a contact value:
Redirect (response='300',
contact='sip:102@host')

The device redirects the call from the sender to a SIP
Recording Server (SRS):
Redirect(response='302',contact='sip:'+header.
to.url.user+'@siprecording.com')
Note:

The parameter can be used for normal and alternative routing.

The response code for redirect messages can only be 3xx.
