3.10.6.13.4. Usage Guidelines
Ringback tone can be heard after a call is sent out from sender’s side by processing audio
packer sent by in-band (RTP channel opened by fast start) from the other side and when ALERT
message is received.
When the system is set at default, ringback tone is generated and heard by receiving ALERT
message and announcement through in-band or tone is received. When the other party progress
indicator information elements are configured with “inband announcement available ,“ the
ringback tone inside is not generated.
If you want to generate a virtual ring tone right after sending SETUP message, set up
local-ringback-early. If you want to hear only announcement to tone, which is delivered by
in-band, set up no local-ringback-tone?
