You included the 'c' option to ReceiveFAX, telling it to act as the 
'caller', even though it isn't the caller. This argument is parsed by 
ReceiveFAX in spite of it not being supported because the older app_fax 
version did support it, and we didn't want dialplans that included it to 
silently ignore the 'c' option. The same is true for the 'a' option; 
you'll note that neither of them are included in the documentation for 
the ReceiveFAX and SendFAX applications, and shouldn't be used.

Why did you specify the 'c' option?
