  • 1.  Voice VLAN QoS

    Our VoIP phones are connected to a VoIP router (not on the company network), then uplinked to Aruba 2930F switch.  Then there's a connection from back of the VoIP phone to computers for LAN.  Occasionally (may be once a month), the phones show unregistered, but the LAN connection to computer stays up.

    What could cause this?  I don't have any QoS in the Voice VLAN.  

    Does this sound like a QoS issue and not a connection issue?

    Do I need to set the Voice VLAN QoS priority to something like 6?  Since 7 is the highest?

    Just a suggestion:
    - prioritize traffic from the Voice VLAN and the correct DSCP/802.1p values. (something like)

    qos type-of-service diff-services
    qos dscp-map 46 priority 6  # 46 = EF (Expedited Forwarding) for RTP audio

    vlan <VOICE_VLAN_ID>
        qos priority 6

    - if your phones support LLDP-MED, they may request priority from the switch.

    Also, DO NOT USE priority 7, since it is reserved for network control traffic. Use Priority 6 for RTP (voice/audio), Priority 5 for signaling (SIP, SCCP), Priority 4 or lower for normal data.
