[asterisk-ss7] Trixbox, Sangoma A101 and libSS7

[Jean Cérien]

not 100% sure, but I have doubts that having

span=1,1,0,ccs,hdb3,crc4

on both side is correct - you should have span=1,0,0,ccs,hdb3,crc4 on one
side - so one clock is master and the other slave

occasionnally, I've noticed than a reboot when changing these parameters has
proven more effective than a simple dahdi_cfg.
