<p>Hi all<o:p></o:p></p>
<p>We had a SS7 link with our provider here in Canada. Everything went well.<o:p></o:p></p>
<p>But they are saying that asterisk is missing the SLC parameter when sending
messages like LUN or LUA etc..<o:p></o:p></p>
<p>So, this make asterisk not compatible with the SS7 protocol. In the debug
message they send us from their switch, <o:p></o:p></p>
<p>You can see that asterisk is always sending a SLS parameter as SLC.<o:p></o:p></p>
<p>Do you know how we can fix it ??<o:p></o:p></p>
