I’m running the most recent version of Trixbox before it went private. It has been running for years without incident using Unlimitel (unlimitel.ca) but, recently I added an 888 number so that there is the main number and an 888 number configured on the system. I can call either of them fine but when someone is on the phone the 888 number gets a busy signal or call failed. Has anyone seen this before? Does anyone have a recommendation for where I should look?
