Looking for a bit of assistance with some configuration. Am i missing or mis-configured something here? If any other debugging is needed pls let me know. I ahve attached a ccapi inout debug of a fax transmission
The issue is that the fax keeps coming back with busy message. It can however receive faxes with no issues and the number is not busy as we provide the DDI.
When the user sends the fax I can see the call being set up and billed for meaning the connection has been established but the fax transmission itself fails.
The router hosting the fax is using h323 and the fax is termination on a SIP trunk.
