Powerful communications with a small business price tag

The SL1100 is a cost effective and powerful communications solution specifically designed with the small business in mind. We do not do much inter-vlan routing accept for administration.Up to 12 PSTN lines, 30 ISDN lines, 32 SIP trunks, 24 digital and/or 40 IP extensions I prefer to do this at the Phone and SV9100 system side. There are managed switches that will automatically detect that you are connecting a VOIP device and tag its traffic as VOICE and place this traffic in the VOICE VLAN you have designated. I agree with M to just use one switch for both traffic and let the VLAN tagging separate the traffic. One of the most common errors I see is that the uplink port don't have access to both VLANS so the VOIP VLAN cant reach the Firewall / Router. You do need the ability to route traffic between VLANs and our firewall takes care of that. The SV9100 must have a static IP Address but the phone can use DHCP. Our phone have a second port on them that we use for the PCs and theses ports have VLAN disabled so they use the default VLAN. The interface on the SV9100 and the phones have the ability to tag their traffic with the VOIP VLAN.

90% of the switch pots are programmed to have access to both VLAN and our firewall provides the inter-vlan routing and DHCP for both VLANS. We use separate VLANs for our VOIP and data traffic and have a SV9100.
