[asterisk-dev] setting the q.931 "reason for redirecting"?

[Roy Sigurd Karlsbakk]

Hi

To answer this myself, setting PRIREDIRECTREASON is not supported in  
1.2, but is/will be in 1.4. I took a look at the code, as to check if  
backporting it looks hard, and it doesn't. however, something is  
wrong so my code can't get what PRIREDIRECTREASON was set to. Can  
someone give me a hand here, please? Patch is attached

Dialplan:
...
exten => _XX.,n(dialgsm),Set(CALLERID(rdnis)=${PSTN_NUMBER})
exten => _XX.,n,Set(PRIREDIRECTREASON=NO_REPLY)
exten => _XX.,n,NoOp(PRIREDIRECTREASON=${PRIREDIRECTREASON})
exten => _XX.,n,Dial(${TRUNK}/${GSM_NUMBER},${DIAL_TIMEOUT},t)


Console output:
...
     -- Executing Set("Zap/1-1", "CALLERID(rdnis)=21973552") in new  
stack
     -- Executing Set("Zap/1-1", "PRIREDIRECTREASON=NO_REPLY") in new
