forked from Mirrors/freeswitch
OPENZAP-238: [freetdm] Several core and gsm improvements
* Add error handing in mod_freetdm for ftdm trace failures * Allow freetdm signaling modules to specify a destroy function * Added conditional forwarding to the freetdm gsm module Just specify the conditional-forwarding-number gsm parameter in freetdm.conf.xml * Added new 'gsm call' freetdm command for raw GSM calls which can be used to enable/disabling network features (e.g call *93) without having to resort to use a full originate that requires routing the call somewhere when answered * Miscelaneous cleanup of piggy coding style left over by one of the previous authors -_-
