HI guys. I hope for ur help . i have such diagram : IPOffice500(LAN:172.16.2.220, WAN:192.168.15.110/24)<->Cisco881(WAN:192.168.15.1, interface vlan20 : 192.168.20.1)<-> IP phone 192.168.20.2 .
the problem is ip phone cannot discover IPOffice. I put PC instead of ipphone with static ip 192.168.20.9/24 and able to ping 192.168.20.1, 192.168.15.1 but can not 192.168.15.110 and 172.16.2.220. then I put PC to lan port of IP office500 with 172.16.2.9/24 and able to ping 192.168.20.1, 192.168.15.1 but can not ping 192.168.20.2 or .20.10 , tracert go till .15.1 ; it's look like there is not route between .15.0 net and .20.0 network but I have configured interfaces in router and they are directly connected . Also IPOffice has route to 192.168.20.0 /28 trough 192.168.15.1 , and configured LAN& WAN interfaces. here are configs on cisco:
