As long as dial-peers are programmed to gateways, etc, then things will work. So, this means, if a phone can't talk to the CUCM, but the SRST router can, you will have phones registering, but not able to dial off-net because the router's gateways are still registered to the CUCM, not the router.<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: "Philip Walenta" <pwalenta@wi.rr.com><br>To: "Robert Kulagowski" <rkulagow@gmail.com>, cisco-voip@puck.nether.net<br>Sent: Wednesday, September 2, 2009 4:58:25 PM GMT -05:00 US/Canada Eastern<br>Subject: Re: [cisco-voip] IP overhead paging: likes and dislikes?
