<p>Hi<br>
I'm using Opensips 2.2 (updated last week) as an outbound proxy using  topology-hiding module.<br>
I see when opensips received an INVITE and topology-hiding is activated (calling topology_hiding()), Opensips doesn't send back to the caller a 100-Trying response, causing re-INVITEs retransmission until the first provisional response from the called endpoint is received.</p>

<p>Thanks</p>

<p>Alessandro</p>
