Disabling Call Waiting

Depending upon the devices connected to the analog telephone ports, it might be necessary
to disable call waiting, for example, if the tone generated by the call waiting service
interrupts data transfer when using an analog fax machine connected to the router. (Consult
the instructions provided by the manufacturer of the device to determine if this is
necessary.)
The set callwaiting command disables call waiting for the analog port specified. Following
is an example of the set callwaiting command that turns off the call waiting feature on the
phone1 port:
766> set callwaiting interface phone1 off

Disabling Call Waiting on a Per-Call Basis

When making an outgoing voice call over one of the analog telephone ports, you might
want to disable the call waiting feature on a per-call basis. To disable call waiting, use the
dual tone multifrequency (DTMF) command, dialed on the keypad of the telephone, as
shown in the following example:
**99#
When the voice call is completed, call waiting is restored.

Call Hold and Retrieve

Call hold and retrieve is the ability to place a caller on hold, make a second call, and return
to the first call. (Some countries that use the NET3 switch do not support ISDN
provisioning for call hold and call retrieve.)
To place a call on hold:

Perform a short on-hook (quickly press the telephone receiver button once) to
get a dial tone.
If your analog telephone device offers the option, you can press the Flash key
instead of the short on-hook to put the call on hold.
Dial the hold access number, **95#.
Dial the second call.
