[Asterisk-Users] Generate ring while waiting for SIP connection to initiate

[Nick Kartsioukas]

We're passing PSTN traffic on to a SIP proxy.  The SIP phone customers
have voicemail that will answer if their phone isn't picked up in a
certain amount of time.  However, if their phone is not on the network,
a caller will get nothing but dead air as Asterisk keeps attempting to
initiate the SIP connection.  Is there a way to generate a ringtone for
the caller while Asterisk is trying to make the SIP connection?
