Dtmf caller id help in Saudi Arabia

Hello
Since a months I am trying to configure the callerid for Saudi Arabia with TDM400P without success, my configuration for zapata.conf as following:

usecallerid=yes
cidsignalling=dtmf
cidstart=polarity

Is there any way to check the PSTN signaling type and who configure it?

Is this the only thing you have tried? Maybe you can take out this line and see what happens. (Not many places use DTMF for CID, but it’s best to ask the telco.)
