Hi lizhong zhu The problem is that link 'l2' belonging to linkset 'siuc' does not have a signalling channel, and signalling from telco side goes through link 'l1'. To solve this, you need either signalling on 'l2', or a patch to chan_ss7 that handles 'suic' and 'jinan' as a combined linkset with a shared signalling link.
