Added support to the libpri API to control the inband audio available
progress indication ie on the SETUP_ACKNOWLEDGE message.
* Added the progress indication ie progressmask value to the struct
pri_event_setup_ack so the PRI_EVENT_SETUP_ACK event can indicate when a
SETUP_ACKNOWLEDGE comes in with inband audio (ie dialtone).
* Added pri_setup_ack() so when the SETUP_ACKNOWLEDGE message is sent it
can indicate if inband audio is present (ie dialtone).
This patch and a corresponding change in Asterisk work together to allow
Asterisk to control the inband audio available progress indication ie on
the SETUP_ACKNOWLEDGE message when dialtone is present.
