CAMA Trunks-reversal of tip and ring wire connections...
When I was going through Cisco Voice GWs and GKs book, I have read through the following.
When CAMA trunks configured with reversal of TIP and RIGN wiring connections to the PSTN, the voice call will go through but it will get disconnected after 15-30 secs with an error of "Timeout to receive signal from PSTN to send ANI (calling number).
Here is my query. When loopstart trunks have TIP and RING wire connections reversed, then will the voice call succeed first of all as it is a signalling mismatch with PSTN?
With best regards...
Pls kindly rate if helpful or answered your question.

I think is to do with the CAMA trunk needing to observe the correct tip & ring (+ve & -ve) polarity as it depends on receiving the "line reversal signal" on called number answer to ensure that the ANI (CLI) is passed to the service.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
