[asterisk-users] DTMF-CallerID on POTS

[Greg Delgado]

Has anyone got a working analog connection to POTS
wherein DTMF, *not* FSK is used to send caller id by
the telco switch towards asterisk?

I've tried Asterisk 1.2.10, SVN trunk, and SVN branch
but so far has been unsuccesful.

When asterisk receives a call, I can see from DEBUG
that chan_zap is able to pick up all DTMF digits like
so:

Aug 11 17:06:17 DEBUG[5113]: chan_zap.c:4624 zt_read:
DTMF digit: D on Zap/1-1
Aug 11 17:06:17 DEBUG[5113]: chan_zap.c:4624 zt_read:
DTMF digit: 0 on Zap/1-1
Aug 11 17:06:17 DEBUG[5113]: chan_zap.c:4624 zt_read:
DTMF digit: 2 on Zap/1-1
Aug 11 17:06:17 DEBUG[5113]: chan_zap.c:4624 zt_read:
DTMF digit: 8 on Zap/1-1
Aug 11 17:06:18 DEBUG[5113]: chan_zap.c:4624 zt_read:
DTMF digit: 1 on Zap/1-1
Aug 11 17:06:18 DEBUG[5113]: chan_zap.c:4624 zt_read:
DTMF digit: 1 on Zap/1-1
Aug 11 17:06:18 DEBUG[5113]: chan_zap.c:4624 zt_read:
DTMF digit: 8 on Zap/1-1
Aug 11 17:06:18 DEBUG[5113]: chan_zap.c:4624 zt_read:
DTMF digit: 8 on Zap/1-1
Aug 11 17:06:18 DEBUG[5113]: chan_zap.c:4624 zt_read:
DTMF digit: 9 on Zap/1-1
Aug 11 17:06:18 DEBUG[5113]: chan_zap.c:4624 zt_read:
DTMF digit: C on Zap/1-1

but the number somehow does not get passed to
${CALLERID} variable.

in zaptel.conf:

callerid=asreceived
cidsignalling=dtmf
cidstart=polarity

does someone have a similar system that's working? I'd
like to know which asterisk and zaptel versions you
are running

Thanks,
Greg
