Note: If the community names are forgotten, connect a TTY to the
Voice Gateway Media Card maintenance port. Restart the card. The card
displays the community name on the TTY during start-up.
WARNING
Do not enter the actual value of the subnet mask on the
interface of the SNMP trap destination. Doing so can
cause misrouting of RTP media and signaling, leading to
no speech path between the IP Phones and the Voice
Gateway Media Cards or failure of the IP Phones to
register with the LTPS.
