Telephony Cards - How do I fix issues with ringback with FreePBX and Digium Digital card
Edit your chan_dahdi configuration file and make sure that the context that handles incoming calls from DAHDI is set to [from-pstn-ringback]
Example
Excerpt from chan_dahdi.conf or any of its includes files
context=from-pstn-ringback
signalling = pri_cpe
channels=1-24
Create a new context to handle incoming calls from DAHDI. Add the following lines into extension_custom.conf
[from-pstn-ringback]
exten => _X.,1,Answer()
exten => _X,n,PlayTones(ring)
exten => _X,n,GoTo(from-pstn,${EXTEN},1)
Note: Please be careful when choosing the file that you are going to add the custom changes. FreePBX may revert to its original configuration is the file is recreated, For more information about how to add custom changes to FreePBX please contact FreePBX community.
