elevator -> PSTN -> Asterisk (via Voip to PSTN)) -> SPA112 -> Modem -> Emergency Support console (special construction modem with "handset") Update: I could simulate the internal part with an 20 year old Siemens analogue DECT phone at the SPA112. CallerID (CLIP) works fine after the first ring with "Bellcore (bell-202 or v.23)", "ETSI FSK (bell-202 or v.23)" and "ETSI FSK with PR (UK) (bell-202 + v.23)". Even the CallerID name is shown. When I set to e.g. "DTMF Denmark" the phone shows only "External Call". > What am I missing? > > Regards > Michael Knill > > From: Michael Keuter <li...@mksolutions.info> > Reply to: AstLinux List <astlinux-users@lists.sourceforge.net> > Date: Wednesday, 20 April 2022 at 9:20 am > To: AstLinux List <astlinux-users@lists.sourceforge.net> > Subject: Re: [Astlinux-users] Analogue CLIP (CallerID) > > Hi Michael, > > the „potential“ customer has these modems for a long time, and there are no > alternatives (like SIP) at the market. > > And sure, in SIP I see the correct CallerID, but the modem don‘t see the > „right“ CallerID generated by the ATA. > > Sent from a mobile device. > > Michael Keuter > > >> Am 20.04.2022 um 00:58 schrieb Michael Knill >> <michael.kn...@ipcsolutions.com.au>: >> >> Hi Michael >> >> Just wondering why you need analogue modems to receive the calls from the >> elevators? >> Have you done a SIP Debug of the traffic coming from the SPA112’s to see if >> the number is anywhere in the SIP Invite? >> Do you know the particular standard for this in your country and is this >> supported by the SPA112’s? >> >> I have never used analogue FXO for anything sorry. >> >> Regards >> Michael Knill >> >> From: Michael Keuter <li...@mksolutions.info> >> Reply to: AstLinux List <astlinux-users@lists.sourceforge.net> >> Date: Wednesday, 20 April 2022 at 2:23 am >> To: AstLinux List <astlinux-users@lists.sourceforge.net> >> Subject: [Astlinux-users] Analogue CLIP (CallerID) >> >> Hi list, >> >> I am trying to install an Asterisk PBX for an elevator emergency central in >> Germany. >> The callees are 6 analogue modems who receive calls from the elevators. >> >> The main issue is that the modems need to identify the elevator via a so >> called analogue CLIP (Calling Line Identification Presentation) where the >> calling number is shown to the receiving modem. >> It is not the Asterisk CALLERID(num) but a special "message" which is >> transfered for analogue phones between the first 2 ringings (but I think >> this is generated from the CALLERID(num)). >> There are several different methods for that, that can be set in the ATA >> (Cisco SPA112, latest EOL firmware): >> >> <image001.png><image002.png> >> >> <image003.png><image004.png> >> >> I tried every possible combination of "Caller ID Method" and "Caller ID FSK >> Standard", but without success. >> >> Has anybody on the list made experiences with analogue CLIP? >> >> Michael Michael http://www.mksolutions.info
