hi lars,

what you need is bandwidth management and QoS features in your router. i changed my router firmware with DD-WRT and tailored the ff:

1. SIP and esp RTP are given top priority for transmission
2. Web traffice are given lesser priority, P2P the last priority
3. ACK packets are also given top priority to prevent download overflow

using scripts I found in the web.

another option is to use VLAN to segregate your network. Data VLAN goes to one router and the Voice VLAN to another router.

Currently my LAN is connected to the internet via DSL. The FreeSWITCH box is
on this subnet. To save money, I am moving the data portion of my LAN to a
new ISP and I want to segregate the VOIP to another ISP. I am tired of
having a bad VOIP connection during lengthy downloads.

My VOIP and FreeSWITCH skills are minimal. I have used FreeSWITCH for over a
year in a home/business environment. The only reason it is working is with
the help of this list.

My knowledge of IP is similar. I do not know how to setup a LAN with two
gateways with all nodes seeing one another. I do want to be able to call out
via FreeSWITCH from a softphone on the data portion of the new LAN.

A friend suggested I need a dual ported WAN firewall/router with load
balancing to enable all the nodes to be on the same subnet. Can anyone help
me with suggestions? Is there a consultant I can hire to help with this?

Thanks, Lars
