Limiting ASCII Character Length?

Hi, we are running Asterisk 1.4.43 which hosts a MessageNet server. I was curious if there is a way to limit the number of characters in a caller ID display name to something like 18 or 20? Sometimes we have IDs that are longer than 20 which can cause some issues with our MessageNet server so I’d like to restrict it to 20 characters max. Is there a way to limit that?


Your version is very old but this should work in 1.4
