Routing traffic to different Lans

Routing traffic to different Lans

Routing traffic to different Lans

Afternoon All

hoping someone can point me in the right direction i have a good general understanding of networking etc but my area is in telephony systems.

The problem i have is The ICT company wants The Data and phones on a seperate network which is fine. but due to the conditions of the office there is only one network outlet per desk, but the phones we are planning on providing are dual ethernet. which will work fine on the same LAN.

Whats the best way to use this existing setup, but route traffic to two different LANS? but i would need both networks to be able to talk to each other as there is computer software for phone programming and management that would go on the computer network but need to communicate with phone network.

Many thanks for any help provided

RE: Routing traffic to different Lans


What model of phone are you planning on using - Cisco, NEC, ect? What is your network infrastructure - Cisco, Juniper, ect? The model of phone and the type of network environment you have will dictate the setup.

RE: Routing traffic to different Lans

Thanks for fast reply stunski.

Model of Phone will either Be an LG IPECS LIP 8021D or Avaya 1608's.

The existing network infastructure is not yet in place and as such subject to an open mind.


RE: Routing traffic to different Lans

You need to decide what infrastructure you're going to implement before we can help with a setup, but I would checkout LLDP since most, if not all, vendors support it.

RE: Routing traffic to different Lans

The standard VoIP setup is designed to not require expensive recabling: the single data point at each desk supports the VoIP phone, the phone then has a "PC" port in it that you patch the PC to.
The connection between the LAN and the phone is a single physical link with two VLANs configured on it. The phone uses an IP address in one VLAN to get on the network. The second VLAN is provided to the PC.
Thus the two devices are on seperate LANs.
