[asterisk-ss7] Asterisk/libSS7 functionality question

[Alan McMillan]

I have successfully implemented a limited NORTEL version of RLT on asterisk.
I am using the DMS-250 flavor...  I can try and answer questions.

Yes, this is definitely possible in libss7, although I believe right now 
it takes some dialplan changes to make it work.  Alan McMillan (I 
believe he's on this list) implemented it, so he would be the one to 
tell how to configure it.
