[asterisk-ss7] Chan_ss7.so

[Anton]

Dear Peter,

Please email it to me, and I'll also will have them 
available to the rest of asterisk user over some URL. Also 
having this code emailed to Sifira guys, they may include 
it to the mainline code. Even if not quickly - some of us 
will do that.

Regards!
Anton.
