Dynamic configuration of Voice over IP (VoIP) phones

You can configure a FastIron device to automatically detect and re-configure a VoIP phone when it is physically moved from one port to another within the same device. To do so, you must configure a voice VLAN ID on the port to which the VoIP phone is connected. The software stores the voice VLAN ID in the port database for retrieval by the VoIP phone.

The dynamic configuration of a VoIP phone works in conjunction with the VoiP phone discovery process. Upon installation, and sometimes periodically, a VoIP phone will query the RUCKUS device for VoIP information and will advertise information about itself, such as, device ID, port ID, and platform. When the RUCKUS device receives the VoIP phone query, it sends the voice VLAN ID in a reply packet back to the VoIP phone. The VoIP phone then configures itself within the voice VLAN.

As long as the port to which the VoIP phone is connected has a voice VLAN ID, the phone will configure itself into that voice VLAN. If you change the voice VLAN ID, the software will immediately send the new ID to the VoIP phone, and the VoIP phone will re-configure itself with the new voice VLAN.
