[Asterisk-video] Re: Testing h324m loopback

[Christian Richter]

Hi Matteo,

if you use a hfcmulti based board with mISDN you should set 
option=x,master_clock (in the misdn-init.conf), where X is a TE port 
connected to PSTN to get the synchronization from that port, that might 
help.

I'm very curious to hear if this works :-)

cheers,

Christian
