[App_rpt-users] Alternate port to 4569

Hello, This may be a simple question. In iax.conf, it indicates the default UDP port to bind to (4569). Is it possible to use an alternate port other than 4569 and make change here? In some other post they mention to change configuration on allstar server network settings, but I don't believe that has anything to do other than to download that configuration to the server if requested by me. I know port forwarding needs to change in router and asterisk restarted. Thanks.
