We don't have some features like CallID but I believe that would be fixed with QSIG. But that costs money on the HiCom side.<br><br>If you have these trunks available on both systems, it's usually the easiest to set up. Otherwise, if you have an IP enabled port on your Nortel box, an H323/SIP gateway might be better, but then you have to buy it.;)<br><br><br><br>---<br>Lelio Fulgenzi, B.A.<br>Senior Analyst (CCS) * University of Guelph * Guelph, Ontario N1G 2W1<br>(519) 824-4120 x56354 (519) 767-1060 FAX (JNHN)<br>^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^<br>"Bad grammar makes me [sic]" - Tshirt<br><br><br>----- Original Message -----<br>From: "Micah Bennett" <mbennett@als-xtn.com><br>To: cisco-voip@puck.nether.net<br>Sent: Wednesday, January 7, 2009 2:33:26 PM GMT -05:00 US/Canada Eastern<br>Subject: [cisco-voip] CCM working with Nortel<br><br>
