On the access layer, access switchports can be configured with a 'Voice VLAN,' where the MS will use LLDP to advertise the voice VLAN's ID to the connected phone.

MS: Cisco Meraki switches are standards-based network switches, designed for the access and distribution layers of the network.Link Aggregation and Uplink Preferences.Traffic Shaping for Packet Prioritization.Furthermore, if the MX is responsible for DHCP and network phones support dynamic configuration options, the MX can be configured to use VoIP-specific DHCP options.įor some additional reading on relevant MX configuration and features: In addition, traffic shaping rules can be implemented to prioritize voice traffic above other traffic types. This can be accomplished using uplink preferences under Security appliance > Configure > Traffic shaping. If the MX has been configured with multiple uplinks, especially if those uplinks are being aggregated, it may be prudent to ensure that voice traffic is only using a particular interface. Typically, since VoIP traffic is best segregated to its own VLAN, the MX may be configured with a dedicated voice VLAN (assuming the MX is configured as the network's inter-VLAN router). MX: The MX security appliance functions as a standard stateful firewall, performing inter-VLAN routing for the network.Since Cisco Meraki equipment is designed with network standards in mind, VoIP deployments can typically be run alongside the network stack with no issues: How do I deploy VoIP with Cisco Meraki equipment?
