Hi, Asterisk (with libss7) is a signaling end-point, so you can't have two point-codes - you need an STP (which Asterisk is not) between the two boxes in order to separate the two signaling channels. However you do not need two point-codes for this setup, but simply to define two groups of channels ... from the example in my previous email, change the linkset definitions to: linkset=1 networkindicator=national group=1 context=From_Span1 pointcode=1 defaultdpc=2 adjpointcode=2 cicbeginswith=1 channel => 1-15 group=2 context=From_Span2 cicbeginswith=17 channel => 17-31 sigchan=16 #include ss7.timers linkset=2 networkindicator=national group=3 context=From_Span3 pointcode=2 defaultdpc=1 adjpointcode=1 cicbeginswith=1 channel => 32-46 group=4 context=From_Span4 cicbeginswith=17 channel => 48-62 sigchan=47 #include ss7.timers Now you have 4 groups on the same 2 linksets, which is equal of having two separate linksets on the same signalling link.
