[asterisk-users] Special Information Tones

[Stephen Davies]

Hi,

Are you sure that Verizon amswers the call?  They should play that
message as 'early media' without answering, after which they cam clear
the call with an appropriate cause code.

That would work for you and still give callers the audible ,essage they want.
