So prototyping; I have a (hopefully) temporary medical condition which makes me unable to work with these small SM components for now. Someone with a supply of passive components and some soldering skill should be able to lay this out on a PCB or even stick the IC to kapton tape and solder required pins with magnet wire to breadboard the seiko pager IC for about $5-10 with several spare ICs.
It should be possible to feed the chip with soundcard audio of the POCSAG signal, even playing a mp3 of the audio should be fine.
Alternatively we could use a fully functioning pager and just tap the serial line comms though that would likely require a SDR or amateur radio transmitter and a pager tuned to amateur frequencies.
POCSAG information and MP3s for testing

The starter app could be a bash script which greps the different parts of the serial output and turns it into a click to modem power-up and dial a dial-able phone number and/or display a SMS like text message.

encoders galore including for gnuradio

this is an alternate IC form Motorola controlled by an ATmega
