Hello guys/gals,
I need your help with a project that has fallen in my lap and can't figure out what to do without paying a lot of support fees. As the subject states, how do I re-route traffic for an existing VoIP system over our existing network.
Host Site Network: 172.23.6.0/24
Remote Site Network: 172.23.7.0/24
VoIP Network: 172.16.0.0/24
Here's a brief background. We have an NEC PBX system at our main site and about 15 VoIP phones at a remote building connected to it via a leased T-1 line from Verizon. There are two AdTran Netvanta 3200 routers sitting at each end of this T1 circuit. The one at host site has IP of 10.10.10.1 and the one at remote is 10.10.10.2. We have an HP Procurve 2610 at the remote site and the PCs and VoIP phones connect to it on the same cable, but at the switch there's a VLAN that handles the VoIP network (172.16.0.0/24) on port# 25 and the rest of the ports are for the PCs (which are on the 172.23.7.0/24 network). We have two Cisco routers (one at each building) that handle all the routing between the two networks/buildings - and that's handled by ADP Networking.
What I want to do is take away the T1 and plug the two AdTran routers into our network. How do I do this? My thoughts were to simply assign the routers an IP address within our network and they should be able to talk to each other. I know I have to worry about some QoS, but that's a secondary issue at this point. Right now, I need to get the routers to see each other.
The reason I've been tasked with this is that the T1 lines is very unreliable - goes down whenever it rains and Verizon's response time is terrible. I know I didn't go into much detail, I simply wanted to be as succinct as possible. Any ideas would be appreciated.
PS. I've attached a network diagram I put together to illustrate the current setup. Below is also a link to the config files for the two AdTran routers
