It is possible through the SmartMedia Web Portal to specify the parameters of ringing, busy, congestion (or fast busy) and warning call progress tones. These settings are available in
Profiles -> Tone Profile Params
The tones are described using a programmable string of characters as defined in the H.248 Dynamic Tone Definition Package. To learn more about tone description strings, see the section below related to this subject.
Examples of Call Progress tones
The following table contains a few call progress tone definition strings that can be used to replace the default ones in the SmartMedia Web Portal.
To learn how to play these tones using the Call Leg API, refer to the Playing and Collecting Tones section.
For example, to play the ringing tone, one could pass either directly ((((#440)+(#480)),2000),(#0,4000))*0 or cg/rt to the AddToneString() function. The cg/rt string refers to the current Tone Profile Params ringing tone setting from the Web Portal.
It is possible to change the ring tone volume. According to the syntax, you need to specify the desired volume after the tone duration. Here is an example: ((((#440)+(#480)),2000,-15),(#0,4000))*0
The possible values are: -19, -15, -10, -5 and 0 dB.
Below is a comprehensive list of all the tone strings that can be passed to the AddToneString() function.
