| Description: | New channel request in dahdi_request currently returns AST_CAUSE_CONGESTION for group matched with no channel available, but returns AST_CAUSE_BUSY for channel matched. This is fine for non-trunk channels, but breaks dialplan logic for trunk channels (e.g. FXO with fxsks signaling), because AST_CAUSE_BUSY is interpreted as "unable to reach party by any means" and terminates trunk hunting logic e.g. in FreePBX. The corrected cause, AST_CAUSE_CONGESTION, is interpreted as "try another means to reach party", resulting in selection of next priority trunk as intended. This patch uses the ISTRUNK() macro to determine the cause:
ISTRUNK(p) ? AST_CAUSE_CONGESTION : AST_CAUSE_BUSY | ||
