My customer got a requirement for T38-UDP ports range needs to be in between 10000 and 20000 range.
On Asterisk, the default UDPTL port range was UDP ports 4000-4999. I have modified this Port range through Asterisk’s udptl.conf file.
However, Asterisk still use the 4000 range for T38-UDP packets.
Is there any other configuration change is requires to take new port range effective? Please confirm.
