Welcome to my telecommunications site. This site will assume that I have acquired FSP Realty. Now, you might be asking why not put this in my .homes domain? The reason is simple, and this exchange will not be used exclusively for the realty company even though the realty company is a condition of having the telecommunications system that I would note in this site. This is because the realty company in its own right will take about 10% of the numbers that I would have.

In the NANP, the 4th-6th digits of the telephone number is known as an exchange. For this to work, I will need to acquire a dedicated exchange. Since 555 is noted for fictional numbers, I will note my phone numbers with the 555 exchange. I will obviously receive a different exchange, and I will hope for the exchange of 377. The reason for 377 is on the US dial pad, FSP is dialed as 377. This will make much more sense than another exchange since it will be me that would essentially pay for the numbers. With that said, there will be 10,000 telephone numbers available, and I will assume $20,000 for the numbers. While I would like to acquire a 412 or 878 number, I will prefer the 377 exchange even more so. If I can’t get the area code (first 3 digits), and exhange I will want, then I will acquire an Allegheny County local number with 377 7368 as the realty’s phone number. This will spell FSP Rent which will make sense for the realty company.

Most of the numbers will either be a forwarder number, or a SIP^? line. This will be essential to know, and if there was a number that would be a cellular number, then when that number is not paid for with service, then the number will return to my control panel where I can decide what to do with that.

Since the numbers are likely to be SIP, I will require a SIP server. The SIP server will be internet connected, and all devices will use a building wide phone network which will be limited. In example, an employee will be able to go to any property, and connect with their wifi phone as each property will use the same wifi^? SSID^? and password. In the end, it will be me that would decide where numbers are directed to.

Any number not assigned will get an “Number Not in Service” error message. This is designed to not waste the caller’s time by listening to a phone ring, or customer hasn’t setup voicemail when there is no number assigned to anyone. Once a number gets assigned, the PIN will be the same as the subscriber number (last 4 digits of the phone number) which will prompt for the system to require that the user change their PIN to a number not the same as the subscriber number.

Since the phones will likely use a SIP server, that server will also support faxes. When a person receives a number, they will provide their email address. This address will be where the SIP server will send incoming faxes to the user. Tenants will not be able to send outgoing faxes, but employees will as long as the email address is a fsp.homes, or fsp.ph address.
