Ham Shack Hotline is a cloud based VOIP service that is just for Ham Radio operators. You must be a licensed Ham to get an extension on the system.
We already have our own asterisk based PBX running and phones are our repeater sites.
We are going to investigate connecting our system to theirs so our phones can connect to the Ham Shack Hotline.
We currently only have one phone connected directly to the Hamshack Hotline.
