[asterisk-dev] Dial() generating ringback until answer or early media

[Alec Davis]

I've updated http://bugs.digium.com/view.php?id=14504 to include option 'R'
but I've run out of evening here in NZ.

We are using Dial option 'r(tone)' which works better for us, as we need to
be able to signal 'Congestion' to the calling switch if Asterisk cannot
deliver the call.

Option 'R' will indicate 'Ringing' to the calling switch, which then will
not (in our case) failover on non delivery to the more expensive Telco
provider.

I was unable to exhaustively test the Early Media aspect.

Yes, that sounds good. I think a new option is needed, e.g. e (like early
media).

e([tone]): If a tone is specified, it behaves like your current patch and
generates a certain tone. If tone is not specified, it will generate the
tone dynamically based on the control frames received on the outgoing
channel. (AST_CONTROL_RINGING -> ring, AST_CONTROL_CONGESTION 
-> congestion)
