Remote iPECS Phone & Remote Services Module
A remote device, iPECS Phone or gateway Module, registers with the system using the device's MAC
address. The MAC address must be assigned in the system database, and the system's IP address must be
assigned to the remote device. For using the address, the remote device will attempt to register with the
assigned iPECS system. When the system receives the registration request, the MAC address is compared
with the database to authenticate the remote device. With a matching MAC, the system will accept the
registration request and provide the remote device with the appropriate settings. Note that the position of the
UCP Registration switch does not affect remote registration.
iPECS Softphone or SIP Phone
iPECS softphones (iPECS UCS Client) and SIP phones register with the system employing the User Id and
Password. When the system receives the registration request, the Id and password are compared to the
Station Login parameters. If a match is found in the Station Login Table, the system registers the device and
assigns the phone the Station Number requested (Desired number), if available. As with remote registration,
the position of the UCP Registration switch will not affect Softphone or SIP Phone registration.
iPECS system
When power is applied, an Ethernet link is established, and the Registration switch (UCP DIP Switch position
3) is in the ON position, the UCP will send a Multi-cast request to unregistered gateway Modules and iPECS
terminals for registration.
When the system receives a valid registration or discovery request, and the Registration switch (UCP DIP
Switch position 3) is in the ON position, the system will respond to the gateway Module or terminal with a
Registration command including the system IP and MAC address. During the registration process, the Module
or terminal will receive data from the system, including a Sequence Number, IP address, RTP characteristics,
etc., as well as default settings appropriate to the type of Module or terminal. Once registered, the Module or
terminal will maintain the system IP and MAC address in non-volatile memory and will not attempt further
registrations. If the Registration switch is in the OFF position, the system will not respond to normal
registration requests from a local device.
Sequence Number
Sequence numbers are allocated to the different device types and are assigned sequentially to devices of the
same type, as shown in Table 2.3.1 below.
