Hi,<br>
<br>
According the the messages below you received a Status Indication "Out
of Service" from the remote end.<br>
You need to check what is happening at the remote end and why they are
sending a SIOS to you.<br>
<br>
Best Regards,<br>
Amish<br>

Can you post the ss7.conf file. <br>
Can you provide a diagram of the flow of voice calls and signalling?<br>
How are you generating the call traffic?<br>

1366 and sent to 1304. How many signalling links do you have?<br>
I assume you have chan_ss7 at 1366? What protocol stack do you have at
1304?<br>
Where in the trace do the links fail?<br>
I see that at packet 954 and and 956 you receive a TFP, for point code
1538.<br>

Thanks everybody for your response so far.<br>
<br>
however, after loading the call to certain 78 simultaneous calls and
the signalling just failed and the dump is as attached.<br>
I tried disabling the sltm, asterisk refuse to start giving me the
error "unknown options".<br>
<br>
kindly help.<br>
