Hello: My customer installed Sangoma A200 with FreeTDM. A200 can not get the callerid in dtmf format, But if the callerid send by FSK format, the callerid can be received. I also take a loot at the code for callerid process in freetdm, it seems lack of supporting the callerid in dtmf format. Mr.Moises also mentioned that three year ago: http://freeswitch-users.2379917.n2.nabble.com/Caller-id-on-incoming-FXO-with... I am not very sure the problem is still there. I post this issue to with logs, please help me check that: https://freeswitch.org/jira/browse/OPENZAP-235?jql=project%20%3D%20OPENZAP%2... I think callerid in dtmf/fsk format should be a standard feature, hope it can be resolved soon.
