I have a working Asterisk VOIP system ( Elastix). I have a Sangoma card with 4 PSTN lines installed. Caller ID from National Carrier is working on analogue phones. when connected to Sangoma Card it works 30% of the time, sometimes showing caller ID, sometimes not. it must be a setting in the conf files and card settings.
I need someone who is familiary with those parameters to fix my issue.
