CallerID sometimes works with my TDM11b card. The line is a KPN line. My analog DECT phone receives the CallerID every time, flawlessly, so it seems to be transmitted reliably. Here is my zapata.conf:
[channels] usecallerid=yes cidsignalling=dtmf cidstart=polarity relaxdtmf=yes busydetect=yes busycount=3 echocancel=yes signalling=fxs_ks context=vastelijn-in callerid=asreceived rxgain=10 channel => 1 signalling=fxo_ks context=thuistelefoon callerid="Telefoon" <40> cancallforward=yes rxgain=0 flash=300 threewaycalling=yes transfer=yes channel => 2
Does any of you have an idea on how to improve? I’ve already tried “cidstart=polarity” and “cidstart=ring”, with and without “relaxdtmf=yes”, all with unsatisfactory results.
