[asterisk-ss7] REL message with modified Redirection Number

[Saeed Ahmad]

Dear Tian,

latest libSS7 will not work with asterisk
please svn following:

svn co http://svn.digium.com/svn/libss7/branches/1.0/ libss7-stable

also note that you have to install dahdi first, then libss7 and asterisk at
last.

PS: Guys any help regarding my question?

Kind Regards
- Saeed
