It would certainly break most of Asterisk's architecture, make CDRs  
hard to parse and cause havoc in the internal bridges.

Do remember that we're a multiprotocol platform. The cause codes needs  
to correlate. You can't set one cause code in a channel driver and  
have a totally different one in the bridge to the other side, which  
might use a totally different channel driver.

What we can do is open up the translation tables between SIP and ISDN  
causes and add some custom codes that you can configure for your own  
use. That would be a bit more clever approach.

Sorry for being harsh, but this has been discussed many times and I am  
still afraid of opening up this pandora's box. The multiprotocol  
architecture is a foundation for Asterisk's success story. If we start  
breaking it apart by allowing too much protocol specific stuff into  
the core, like the dialplan, we're not multiprotocol any more. There  
are many platforms out there that are single protocol. Many of them  
being replaced with a multiprotocol engine like Asterisk ;-)
