Hello, to illustrate the new feature got by Kamailio to use names instead of integer index when defining/calling route blocks, I have updated the default config posted to the wiki: https://sip-router.org/wiki/migration/kamailio-3.0-config The workaround in the past was to use M4 or other text preprocessors, now can be done directly. It looks nicer and makes the config more human understandable. Happy testing, Daniel -- Daniel-Constantin Mierla http://www.asipto.com/
