At the moment, we are unable to provide an update for when LLDP will be implemented, unfortunately. Lansweeper should still be able to pull data from the VOIP phone however if any of the following protocols are enabled on the phone: FTP, HTTP, HTTPS, JetDirect, MOB (Managed Object Browser), SIP, SMTP, SNMP (SNMPv1, SNMPv2 or SNMPv3), SSH, Telnet or WMI.
MAC addresses specifically can only be retrieved for network devices at the moment if the device is in the same subnet as the Lansweeper server or has SNMP enabled. Port/interface information is pulled from SNMP for network devices as well.
