asterisk users - Jul 2005 - asterisk and wireless on site personal paging system

hi,

we are currently planning are large site which will migrate from an old 
siemens hicom pbx to asterisk.

the customer is currently using a paging system (small receivers which 
display a callback number and a base station (transmitter) with several 
antennas at the site)
the problem is, that the currently operative base station uses 4 ISDN 
BRI interfaces. But the protocol is old germany 1TR6 (and not EuroISDN).
- is there anybody with experience on these pager devices? do they have 
a common standard?
- does anybody know of a pager base station with an SIP interface?
- does anybody know of a pager base station with an EuroISDN interface?

what's your general advice on those paging systems?

regards
  frank sautter

Did you try contacting the vendor of the base stations to see if they
have a EuroISDN firmware update? My Eicon Diva Server BRI card supports
the 1TR6 protocol. The firmware can be found here:
ftp://ftp.isdn4linux.org/pub/isdn4linux/utils/eicon/firmware/
Perhaps AVM supports 1TR6 too.

Nope.

yes, eicon diva server supports (we also have one here) but i was not 
able to load the capi drivers upon the 1TR6 stack?!?
the next problem would be, that we need a isdn interface in NT mode, 
which is (to my knowledge) only possible with the cologne chip cards 
(junghanns / beronet).
so i think we need an new solutions with the old wireless pagers.

is there anybody who has experience with http://www.ascom.com/ws ?
