A kids school that use trixbox and shang332 in Canada case study
This Kids school has 3 school in 3 cities. They want to connect them over the internet to make free internal call. And they want apply more phone number to provide better service.First location - about 30 extensions, second location - about 20 extensions and third location - about 7 extensions.
What devices they used
They installed a trixbox server in the head office, use a shang332 28fxs4fxo for their 30 extensions. Use a Jin302 phone for the reception.
They applied some DID number from didww.com, and connect the old pstn number to the shang332’s fxo port. Connect all those device into the internet by an ADSL with static public IP.
In the site 2, there are an shang332 12 fxs4fxo for extension and pstn , and an Jin302 phone for reception.
In the site 3, because there are only 7 extension, so they all use ip phone Jin301 and Jin302.
What function they get
By those DID from didww.com, they have many phone number at low cost about $5 for a number per month. The trixbox support many sip lines capability.
When their customers call to those DID, they will be accessed to the trixbox’s welcome message. After that they could dial extension number to reach yips’ office in 3 places. If the caller select 0 for the reception, the reception’s Jin302 ip telephone would ring. After the reception pick up the phone, he/she can transfer to the other extension.
For those employees, they can make voip call and also pstn calls.
This gateway provides pstn failover. Normally, they can call by trixbox, when the sip service provider is down, they could choose different router to make pstn call. Even when the power is lose, there are still 4 lines are live for pstn calls.
