The issues are: Dial out from either line reports the # of line one. The programming of the alarm fails after about 30 seconds. It shares a line with a fax machine. These are the voice configs of the two routers: FXO Router Voice config: voice-port 2/0 connection plar 7707545544! voice-port 2/1 connection plar 7707545738! dial-peer voice 1 pots destination-pattern .......... port 2/0! dial-peer voice 2 voip destination-pattern 7707545544 session target ipv4:10.50.100.21 ip qos dscp cs5 media! dial-peer voice 3 pots destination-pattern ........... port 2/1! dial-peer voice 4 voip destination-pattern 7707545738 session target ipv4:10.50.100.21 ip qos dscp cs5 media FXS Router Voice Config: dial-peer voice 1 pots destination-pattern 7707545544 port 2/0 dial-peer voice 2 voip destination-pattern ………. session target ipv4: 10.50.100.20 ip qos dscp cs5 media dial-peer voice 3 pots destination-pattern 7707545738 port 2/1 dial-peer voice 4 voip destination-pattern ……….. session target ipv4: 10.50.100.20 ip qos dscp cs5 media VOICE TOPOGRAPHY Voice originates with either Cbeyond VOIP IAD or ATT copper. One copper line goes to both our FXO Router and to a fax machine. The other line comes out of the Avaya phone switch as analog and goes to our router. The router is 100 BT full duplex into a Foundry switch. It goes from there through single mode fiber to the portable classrooms. There it goes into another Foundry switch to our second Cisco 1751V router. The router has two FXS ports that go directly to the alarm panel.
