Browse All TopicsI am constructing a network for a small office. The company requires MS Small Business Server and will also use IP telephones. Two ADSL connections are provided, one for Voice, and one for Data.
I have implemented both these technologies before, but not on the same site.
For SBS, I would normally configure the Small Business Server to act as DHCP for the network. The SBS Server would sit between the ADSL router and the network switch, essentially, all network traffic travels over the SBS server.
For IP Phones and a non-SBS network, I would normally have an ADSL Modem/Router for each connection, only one router providing DHCP for the network, and would use an intermediate switch to ensure that data is routed over one ADSL and voice over the other.

The question I have is:
What will be the impact or challenges associated with turning off the DHCP on *both* routers and using SBS as the DHCP for the phones as well. In particular, will the SBS server interfere with, or bottleneck the voice traffic.
My current opinion is that the SBS server should not sit between the phones and their switch. For this reason, I intend to install the server on the LAN side of the switch, although this will require firewall configuration to expose the external part of SBS (mail/web server) to the internet.
Anyone done this sort of set-up before? How did you approach it?

I agree that the phones should not be going through the SBS server, and the router config sounds OK.
DHCP on the server should reserve fixed IPs for the phones.
I hope this helps !
