daubs8 Posted July 16, 2008 Share Posted July 16, 2008 I need to find the number of a site calling our monitoring station every 30 secs via ISDN. My idea is to put an ISDN phone on the line with caller display. Where can I get one?? Google has a company but out of stock. Any suggestions??

Lectrician Posted July 16, 2008 Share Posted July 16, 2008 do your cal logs show the originating number? Your system will log it, assuming you have caller id enabled Most systems will forard caller ID these days to both system phones and SLT's. Have you got caller ID enabled by your supplier (bt?).
