[Freeswitch-dev] Channel variables from openzap

I want to access channel variables from an ozmod module in openzap. I can't see a way to do it in the current code. I'd like to add the feature and provide a patch for openzap when I'm done. I'm thinking of adding a void pointer that could be passed down via zap_channel_open that could be then be used from the ozmod modules? Mod_openzap would set the pointer to a function that would give access to channel variables. Thoughts? Simon
