Hi,<br><br>Not sure if it is a bug, but chan_dahdi.so fails to load if res_smdi.so is not loaded before, throwing the following error:<br><br>loader.c:417 load_dynamic_module: Error loading module 'chan_dahdi.so': /usr/lib/asterisk/modules/chan_dahdi.so: undefined symbol: ast_smdi_interface_unref<br>
loader.c:653 load_resource: Module 'chan_dahdi.so' could not be loaded.<br><br>The above occurs in Asterisk SVN-branch-1.6.1-r186527<br><br>Regards,<br>Chris<br>
