Hi all,   I setup a lab, created a sip trunk between UCM and Trixbox.   Extension 2001 and 2002 in UCM. (using SCCP) Extension 3001 and 3002 in Trixbox. (Using SIP)   I maked a call from 3001 to 2001 via Sip Trunk, the call successful, from 2001, i tried to transfer the call to 2002 and the problem is here : 2002 take the call from 2001 but can't talk with 3001 and 3001 hear the hold music.   Somebody have ideal about this?
