Hi I connected 2 asterisk server with libss7 together to simulate real scenario. There is one signaling link between . Asterisk one has one opc11 but Asterisk two have two opc2_1 and opc2_2. There is 2 spans between , and I want to first spans use opc2_1 and second span use opc2_2. For setting Asterisk one there is no problem , in same linkset I can add new defaultdpc=3 and new channels and new CICs. but in second server how I can add CICs ,here I should separate add CICs based on pointcode (opc2_1 and opc2_2) but it seems one link set just accept one point code. If I want to add linkset with new pointcode(opc) with same signaling channel it is not possible. how I can have one signaling link but multiple originate point code in different channel groups ?
