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 the Table 2.3.1 below.
