[Ngo-Vi Hoai-Anh]

 Hi,

Linkset??? Should be host configuration. I assume the linkset 
configuration is missed in your ss7.conf

There should be channel configuration in zaptel.conf as well. Please 
take a look at my working configuration below.

I have a single E1 card. The  C7 signaling is at channel 16 on port 1 of 
the card. My zaptel.conf reads:

span=1,1,0,ccs,hdb3,crc4
bchan=1-31
span=2,0,0,ccs,hdb3,crc4
bchan=32-62
span=3,0,0,ccs,hdb3,crc4
bchan=63-93
span=4,0,0,ccs,hdb3,crc4
bchan=94-124

my ss7.conf reads
