Defining two routers on same LAN and 2 WANs

By levyron ·

I am trying to add a WAN connection to a customer VoIP deployment so Voice traffic could go through a separate WAN connection (will not go on the existing WAN connection where data is carried) instead of PSTN line. Does anyone know how to configure the two routers that phones will pass through one where SIP trunk is defined and all other traffic will go over the data WAN? Thanks

for the voice traffic.

some of the phones are softphones on PCs that surf the internet through router 1. We have configured them so they register with the PBX and then all PBX traffic goes static through router 2 which will carry the voice. is this what you mean wiht static route out? and then - should the two routers be on the same subnet?

static route for voice traffic. If it was me I'd stick with hardware phones. easier to setup with managed switching and routing. you can create vlans for the phones on the same switch or stacked switches that workstations and servers are on. you can tell the switch to route voice traffic to a particular gateway or specify the static route.

same subnet?

by levyron In reply to yep

from what I hear not only from you, vlans are the most simple way to do so. trouble is that this is a small installation and we thought to do so without managed switches and let the routers do the work. Anyway thanks for helping me out - tomorrow will do this. I just did not understand if both routers need to be on the same subnet?

well vlans are the way to go

by CG IT In reply to same subnet?

and SMB installations can have vlans along with low cost routers that can handle vlans.

The Cisco 2950T 24 port switch is a workhorse and inexpensive. Cisco also makes a SMB router the RLV 200 which can handle vlans.

As to your question, you should have the phones on a different subnet from the computer network. That's what I would do.

Assuming I do have some soft phones will two subnets work? How would the phones on 192.168..pcs recognize a hardware phone with 10.0..aubnet? do I need to do any more configurations?

Thanks for your assistance CG IT.

not a matter of will they work or not

It's a matter of the equipment your using and how that must be configured to provide voice communications.

VoIP providers like Skype use a consumer level DSL connection to provide phone service. for a small business, this might be an economical method because of the low monthly cost virtually no equipment and equipment administration & maintenance cost.

Larger businesses might find that their phone usage competes with their internet usage in an undesirable way. Purchasing their own VoIP equipment might be an alternative however cost wise, adding another DSL line strickly for VoIP services more cost effective. There isn't the capital expenditure for equipment, setup and configuration as well as the administrative effort in maintaining the system. So if your putting in your own VoIP system which costs a lot, the additional expense of $250.00 USD for a managed switch isn't that much compared to the cost of the VoIP system.

I would say, for the cost of VoIP phones, dump the softphones and put the VoIP hones on their own subnet.
