When doing a predictive dialing, calls are not being connected to agents in queue. Following is the error getting
[Jul 5 16:32:26] WARNING app_dial.c: Unable to create channel of type ‘SIP’ (cause 20 - Unknown)
[Jul 5 16:32:26] VERBOSE logger.c: == Everyone is busy/congested at this time (1:0/0/1)
Please advice me to resolve this issue.
