Port Numbering
The phone will provide the ability to configure any TCP or UDP port number
that is currently fixed, with the exception of:
•SNMP
•SNTP
• DNS
•WAP Push
• WAP Push secure.
The table below gives the port addresses that will be configurable. The ta-
ble also shows the default values (see also RFC 1700
– Assigned num-
bers).
In some cases a port base number is used. The port base number will be
the configurable item, not the port numbers derived from the port number
base.
