Overview of VoIP industrial broadcasting telephone PT-IFSP1
They are IP-based Integrated PA & Intercom telephone, which are fully contained in an composite waterproof housing with an automatic shut-off door that provides complete protection against dust and moisture intrusion, resulting in high reliability of the product long MTBF. 
The unique robust handset is manufactured from moulded polyurethane and designed specifically to withstand arduous use in all environments, it can be fitted with an armoured cord, if required, to provide additional resistance to vandalism or heavy industrial use. the VoIP broadcasting loud speaking telephone support POE power supply, support SIP v1 (RFC2543), v2 (RFC3261)

This industrial speakerphone built-in 30W power amplifier,can output more than 100 dB of sound, while supporting a warning lamp, even in the harsh industrial environment, will not miss any calls. we can customize greater amplifier, when the calls in, automatically trigger the broadcast.

It is based on open SIP standards, this means that You can use PSST sip phone with other manufacturers sip server and phone communication free of charge over the internet. because of the international standard protocol also means that the PSST solution is extremely cost effective when it comes to future maintenance and repairs. you can easily swap out the PSST SIP phone or PBX at a later date, without having to worry about being tied to certain phone or switch products via proprietary protocols.
