Can you provide a diagram of the flow of voice calls and signalling? How are you generating the call traffic? >From the trace it looks like all the traffic is generated by point code 1366 and sent to 1304. How many signalling links do you have? I assume you have chan_ss7 at 1366? What protocol stack do you have at 1304? Where in the trace do the links fail? I see that at packet 954 and and 956 you receive a TFP, for point code 1538.

I tried disabling the sltm, asterisk refuse to start giving me the error "unknown options". kindly help.
