The VPN will affect the quality of service, since it goes through an additional set of routers. Dropping the VPN connection in the middle of an active call will cause the call session to be dropped for security reasons.

Some IT administrators can manage VoIP account settings in the BroadSoft portal. Those who have access can login to the BroadSoft portal.

ITS is currently using HP 5130 PoE switches to connect the VoIP phones. These switches are LLDP/PoE enabled for the voice VLAN feature.
There are two modes we can look into:

  • If every user has a dedicated network port to connect a VoIP phone, you can configure each switch port as an access port (untagged VLAN)
  • If users only have single network drop, the pass-through port will be used to connect a computer. We will configure a switch port to be hybrid mode to enable the voice VLAN feature via LLDP.

For switches not supporting LLDP, VLAN discovery mode is an alternative; however, without DHCP server, the VLAN discovery mode will not work. You may refer to this thread in the Polycom Community support discussion board for more information.
