For example, if there are 312 IP sets already registered when you register, your extension
would get port s000313.

IP
For DCP sets, the port can only be assigned once. ISDN-BRI provides a multipoint
configuration capability that allows a previously assigned port to be specified more than
once as follows: 2 stand-alone voice endpoints, 2 stand-alone data endpoints, or 1
integrated voice and data endpoint.
However, for the following cases, the port is assumed to be fully assigned:
- Maximum number of users (currently 2) are assigned on the port.
- One of the users on the port is a fixed TEI station.
- One of the users on the port has B-channel voice and B-channel data capability.
- One of the users on the port has no SPID assigned, which includes telephones that have
no SPID initialization capability.
- This field is display-only for H.323 set types and 4600 set types. The system assigns an
"IP" when the station is first administered.
Note:
Port 1720 is turned off by default to minimize denial of service situations. This
Note:
applies to all IP softphones release 5.2 or later. You can change this setting, if
you have root privileges on the system, by typing the command: /opt/ecs/
sbin ACL 1720 on or off.

Indicates that there is no hardware associated with the port assignment
since the switch was set up, and the administrator expects that the
extension would have a non-IP set. Or, the extension had a non-IP set,
and it dissociated. Use x for AWOH and CTI stations, as well as for SBS
Extensions.
Indicates that there is no hardware associated with the port assignment
since the switch was set up, and the administrator expects that the
extension would have an IP set. This is automatically entered for certain
IP station set types, but can be entered for a DCP set with softphone
permissions. This changes to the s00000 type when the set registers.
