Hello! I'm trying the Express Talk SIP client on Mac and Windows and I experience about 2 seconds delay between saying "ping!" and hearing it on the other side of the line. I'm using Express Talk connected to Hipath 3500 (HG1500 SIP gateway) and talking to other extension telephone. LAN is fast and we don't experience the problem with X-Lite or other clients. What could be the reason? Thanks Gregor
