If you don't fancy using a soldering iron to read UK CLI there's a mod to * that my colleague, Robb Boardman, uses. By placing a certain model of Hayes or Pace modem in parallel with * on the incoming PSTN line the CLI is collected (before the first ring) via a serial TTY port. I'm sure it was posted in here some while ago so if you're interested have a look in the archives or reply to this note and see if we can encourage him to re-post the details. >From memory the new ProSlic chip used by Digium supports UK CLI at a physical interface level but appropriate drivers have not yet been coded. Mark Spencer is very aware of the community's demand for international CLI; I suspect that it's a case of ever growing demand for new functionality verses finite implementation/support resources (both financial and human). If we can obtain the ProSlic technical interface details does someone fancy a spot of coding in return for a bounty...? On the subject of line reversal detection I know of a major manufacturer whose LLU products were recently rejected by a UK Telco for failure to support this feature on V5 Access Network muxes. There were a number of problems with automatic telephony equipment (E.g.. subscriber's own (CPE) telephone answering machines) that could not detect the end of the call. One of the strengths of the PSTN is the backward compatibility that has been maintained (including physical standards like voltages as well as higher protocols) for more than 100 years. I would like to echo an earlier poster's comments about the necessity to maintain compatibility with the earlier electro-mechanical standards for as long as we can. Just my 2ds...

ISDN BRI is two lines - so that makes it £2.50 more per line ???? - or £10 a year..?? no need to purchase the BT50 (a caller-ID unit? - at what cost? you need one per line? and an RS232 interface per unit?) > There was a post on the list in the not to distant past where someone had > written two small scripts for getting the information from a BT50 and a > serial modification and passing it to asterisk. > > Still seems the best way in the interim. > > As has been said many times in the list Digium have given us this software, > we don't have to give them a hard time in return. Not a fair payback. True - the software is excellent. If they sold an ISDN BRI 4-port card (like Fritz) - I'd buy it from them.
