Abstract
There is provided methods and devices for relaying tone events in a communication system. A first tone data indicative of a first tone is received and buffered. Following, a second tone data indicative of a second tone is received and buffered. The first and second tones can be, for example, DTMF digits. A processor retrieves the first tone data from the buffer and generates the first tone corresponding to the first tone data. The first tone is generated for at least a first predetermined period, which can be approximately 50 msec, for example. After the first tone has ended, the processor waits for a second predetermined period before retrieving the second tone data from the buffer. The second predetermined period can be, for example, 50 msec. Subsequently, the second tone corresponding to the second tone data is generated for at least the first predetermined period of time.
