2.  Script migration

2.1  DIALPLAN module

As dialplan depends now on the pcre library, the module is no longer compiled by default, so you need to take care and remove if from exclude_modules list in Makefile. Otherwise, no other changed are required.

2.2  PERMISSION module

If you use the get_source_group() function, you will need to get the output in a different way - instead of using the return code as output, the function now requires a variable as parameter to return the output.

The change is from:

  $var(output) = get_source_group();

to

  get_source_group("$var(output)");

2.3  XLOG module

As the module was removed, after updating from SVN, be sure the directory modules/xlog is completely purged.

In your config, you just have to remove the loadmodule for the xlog module. As the syntax of the functions (now in core) didn't change, you do not have to do any other changes

2.4  DROUTING module

The module parameter attrs_avp has changed to gw_attrs_avp

The change is from:

  modparam("drouting", "attrs_avp", "$avp(dr_attrs)")

to

  modparam("drouting", "gw_attrs_avp", "$avp(dr_attrs)")
