<p class=MsoNormal>Hi all<o:p></o:p></p>

<p class=MsoNormal>We had a SS7 link with our provider here in Canada.
Everything went well.<o:p></o:p></p>

<p class=MsoNormal>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 class=MsoNormal>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 class=MsoNormal>You can see that asterisk is always sending a SLS parameter
as SLC.<o:p></o:p></p>

<p class=MsoNormal>Do you know how we can fix it ??<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>WHAT THEY SEND US :<o:p></o:p></p>
