Asterisk Translations

Hello can you help me with some asterisk translations.

My provider requires my outbound calls to be in format E.164. When my users dial 024800898 and my Asterisk should translate it to 35924800898. How can I remove “0” and add “359” to each call that starts with zero.

This is rather basic stuff.

359${EXTEN:1} as the first parameter of the Dial application.

Corrected missing {

This should read 359${EXTEN:1}
