CTIOS Agent sometimes unable to transfer the call, gets IPCC error 10109 The Number you dialed is not valid for your defined calling plan.
Error code gives a description,
1st Level Text = 'The agent is attempting to make a call that is not valid for their defined call plan'
2nd Level Text = 'The call type that the call was classified into is not allowed forthe dialed Number Plan used'
But couldn't get an idea what is this ?
