[asterisk-users] FW: IPcortex: ERROR[23444] chan_zap.c: You cannot use cause 17 number when in state 6

[Steve Davies]

Xavier,

DoNotDisturb generates a "Busy" indication. Insert that into my earlier
response, and you have an explanation of why the call tries to go from RING
to BUSY, and confirms my theory.

No you cannot replace the Zaptel card driver on its own (and the problem
was bigger than that anyway), as Asterisk is compiled and linked to a
specific Zaptel (Dahdi) version.

As mentioned, you need to call IPCortex.

Regards,
Steve
