system, then leave the asterisk system (as it tries to dial the outside line when reaching the specific extensions 4832), then receiving a disconnect from our asterisk system almost immediately. So it would appear that asterisk attempts to forward the call as expected, then immediately disconnects for some unknown reason, which I guess is the specific issue I need to determine the cause of and resolve. I'm going to try what you've suggested and set the callerid to one of our numbers. Will let you know of the result. Thanks!
