YAYPM:Bridge and then unbridge

This script is given as an example, don't forget to change some information such as yate's extmodule binding ip address and port.

This script will:

• 1 - make a phone call to 'jmfoucher'
• 2 - play a sound to jmfoucher
• 3 - wait for DTMF "1"
• 4 - once "1" is pressed, toto is called
• 5 - when toto answers, toto and jmfoucher are bridged
• 6 - after 3 seconds, toto and jmfoucher will be unbridged (the two new channels are independant)
• 7 - two different sounds are played on the different channels
