Summary:                    incoming INVITE received no progress, just 200 OK,
causing Sipra pstn to go off-hook
Description: 
With a Sipura 3102 using asterisk as its proxy (pstn->voip). the Sipura
sends asterisk an INVITE, then asterisk responds with a "100 Trying" almost
immediately,  but then as soon as asterisk starts dialing extensions to
handle the incoming call it sends "200 OK" to the Sipura.  This causes the
Sipura to prematurely go off-hook.

Shouldn't asterisk be sending a "180 Ringing" to the Sipura until one of
the extensions answers the call at which point the channels would be
bridged?
