[Asterisk-Users] custom ring tone

[Alex Vishnev]

Yes, sometime audio is both ways. Sometimes, it is just one way. This only
works in digital network (T1/E1 to T1/E1 (CAS handoff) - the window is much
shorter even in feature group "D". or T1/E1 to T1/E1 PRI signaling where the
window could be as large as 90 seconds. Again, that depends on country,
provider, switch software. You can't get this if you are calling POTS lines.
