Any reason on the IPO side that an SCN connection will every 5-15 minutes drop and then come back up 5-15 minutes later. I've deleted the lines, rebooted, rebuilt them and rebooted again and the problem persists. The IT guy has rebooted the routers at each location. The curiosity of this is that it never seemed previous to me switching the 0.0.0.0 ip route from LAN1 to LAN2 to accommodate the new remote IP phones that the IT guy could not figure out how to get to work through his Cisco ASA firewall either through VPN or port forwarding. So I bypassed his firewall and gave the IPO a public ip address (and secured it) on LAN2. I also am now routing the the SIP trunks via LAN2. But since then, I have had issues with the SCN line. Here's my config:
