code will be unfrozen in few weeks. As personal preference, returning 
code is a more flexible way, as the config writer can chose what to send.

Changing the return code for a function is not a new feature IMO. 
However, I mean by that to do it with the current design. If I am not 
wrong there is a pipe communication between sip worker processes and 
purple worker processes.

You cannot get the error in purple processes and return it in the sip 
process. What you can do is to have a different reply code if you had an 
error while building the packet for purple process (e.g., no more 
memory) and once you send it to purple process return true and the code 
writer should reply with 202 Message accepted.

Cheers,
Daniel
