FreePBX 2.8 + Dahdi module +Zap Channel DID module

Looking at extensions.conf, there is no context from-zaptel anymore. Instead it is from-dahdi. In Zap Channel DID module, it states explicitly to change the context to from-zaptel. Perhaps adding an alias for from-zaptel to from-dahdi might work?

Thanks for the clarification.

have a look at extensions_additional.conf

in general, from-zaptel, from-dahdi and from-analog should all be synonyms.
