A friend sent me a channel/driver module compiled for asterisk-1.6.1.6. When I tried to load it to an asterisk-1.6.1.10, I got the following error messages:
OpenWrt*CLI> module load chan_xxx.so
Unable to load module chan_xxx.so
Command 'module load chan_xxx.so' failed.
Is there a way to load a channel/driver module compiled for other version asterisk?
