Complete network requirements

Build out the network infrastructure according to the plan established in Chapter 2. Take care to verify that VLANs are configured properly and the QoS settings that will be required by the phones are set up according to the manufacturer's guidelines.

If virtual networks are being established, configure all trunking between switches. The PBX and gateways will not be able to tag their traffic for specific VLANs. Ensure that some ports are available that are natively configured (untagged) to exist in the phone VLAN. It is also a good idea to configure an extra port natively set in the phone VLAN for testing purposes.

If DHCP and DNS services are not going to be configured on the sipXecs server, it is important to have them configured and operational before installing sipXecs.
