Hi guys A variable (e.g. liberal_dtmf) which has an underlying channel flag (e.g. CF_LIBERAL_DTMF) or some other internal representation or associated state can only be set at the beginning of the channel's lifetime, i.e. at the start of the call. What is the best place to add custom code to allow this to happen for a particular variable while the call is in progress? 1. With a variable-specific command (e.g. "uuid_liberal_dtmf <uuid> true") 2. By modifying uuid_setvar to carry out some custom logic 3. With the addition of a new generic command, e.g. uuid_setvar_deep, which could serve as a single point for folks to add their custom code, and to return an error for any variable which is not explicitly supported. Any thoughts? Regards, Richard -- Richard Brady M: +44 (0)7771 623 348 T: +44 (0)20 8144 8160 E: rnbrady@gmail.com
