The Versitle Hardware Integration Adapter for SIP Phone Systems
This is a great award winning product that allows easy custom hardware integration with your SIP based phone system.
At HELIA we use them for paging system, door phones and broadcasting event audio over the phone system. They can be used to drive relays and automate processes. With their strong focus on Snom.io, this device can be a primary IoT interface to initiate both point to point and multicast network traffic as well as webservices.
(TMC’s 2014 Internet Telephony Product of the Year award for its PA1 public address system. – See more at: http://sip-trunking.tmcnet.com/topics/sip-trunking/articles/370213-snom-pa1-wins-internet-telephony-product-the-year.htm#sthash.24UT6sls.dpuf)
the Snom PA one argue adapter is easily installed. Once it's mounted in place, simply attach a network cable that includes the PoE or power over ethernet and the Snom PA one will be powered directly from your ethernet cable.
The IP Reset button can be pressed once the device is powered and the Saddam PA one will read out the IP address over the speaker or line out jack. This makes it easy to navigate and configure the device. Simple open a web browser on your computer that is on the same network and navigate to the IP address you heard.
By default the Snom PA1 does not have a username or password assigned to the web interface. If your device is prompting for a password, simply hold down the IP/Reset button for 10+ seconds while there is power and the PA1 will factory reset itself and clear the password.
This is what we use for broadcast events over the phone system at public venues. See: http://www.businessphonescalgary.ca/broadcasting-church-over-your-phone-system/
