[Asterisk-Users] Voip wifi text pager

[Andres Paglayan]

Hi,

I am looking for, but not able to find:

a wifi voip pager,

meaning a wifi text receiver device which can receive text messages.
I know a wifi voip phone will do, but they cost +$160

it even really doesn't need to be voip,
but if so, it can be integrated within the * PBX and get msgs sent by  
sipsak
or any other sip library,

do you know anything that can work like this? (and cost less than $50  
each)

Thank you,

(somebody can always invent it, and remember me when profits rain)
