governed by a higher level SPP registrar gateway. The Primary Registrar is the highest

Parameters –
Public IP Address
n.n.n.n

SNMP
If you intend to manage your MultiVOIP remotely using the MultiVOIP Manager software, you will need to set
the Simple Network Management Protocol parameters. To make the MultiVOIP controllable by a remote PC
running the MultiVOIP Manager software, check the “Enable SNMP Agent” box on the SNMP Parameters
screen.
The MVP130 MultiVOIPs only have limited SNMP functionality available. Contact Multi-Tech Support for help if
you want to use this.
