I'm not a TDMoE expert but I ran into an issue when using DAHDI 2.4.0 with
dynamic_local spans that would probably affect you if you want to use
dahdi_dummy to provide timing for TDMoE spans.
The quick summary is that if you want to use dahdi_dummy with dynamic
spans, please:
1) Enable dahdi_dummy in drivers/dahdi/Kbuild
2) Comment out the MODULE_ALIAS("dahdi_dummy") in drivers/dahdi/dahdi_base.c
3) Undefine ENABLE_TASKLETS in drivers/dahdi/dahdi_dynamic.c
If you are going this route, hopefully this might save you some
confusion.
Here are the above three steps expressed in a patch:
