Provider telephone lines are coming into a Digium board. IVR answers, Customer dials extension, and then just hears dead air until the extension is picked up or sent to voice mail. Previously, a typical ringing sound would be heard. On internal extension to extension calls (SIP to SIP), ringing can be heard.
Does anyone have troubleshooting tips? Can I provide further information?
The beginning announcement was started late because I was unsure of which DAHDI channel I would hit. I cut out my name and hungup before the entire voicemail announcement was complete. I don’t think there was any cut-out actually occuring.
