Alignment problem with libss7

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have it the other way round, Asterisk is configured as master clock (also
in wanpip1.conf file) and so I have span=1,0,0,ccs,hdb3,crc4 there, and
Mobicents is the slave (TE_CLOCK  = NORMAL in wanpipe1.conf) and so
span=1,1,0,ccs,hdb3,crc4.

So the clock comes from the Asterisk side.
