[Asterisk-Users] Supply ringing noise to IAX callers

[James Bean]

Hi,

Got 2 asterisk boxes, Box 1 has SIP users, and Box 2 has a E1 card
connected to a TDA200, when a sip user from box 1 calls someone on the
tda200 there is no ringing noise just dead silence until the person on
the TDA picks up there extensions.

Is there a way in thse situations to supply a ringing sound to the call
so the user on box 1 doesn't think there is a problem if the phone is
ringing at the other end for 20-30 seconds?
