</div></div></blockquote></div><br><br>Theorically, does the order with which cables are plugged into a box matters (as fas as Termination setting is concerned) ?<br><br>I'm asking because, thanks to your advice, it is working today tough the same settings (it seems) failed yesterday.<br>
<br>For reference, here are my settings:<br><br>AST1 ----<BRI>---- AST2 ----<BRI>---- Patton<br><br>AST1: <br>span=1,1,0,ccs,ami,term,te<br>signalling = bri_cpe<br><br>AST2 (port1 to AST1):<br>span=1,0,0,ccs,ami,term,nt<br>
signalling = bri_net<br><br>AST2 (port2 to Patton):<br>
span=2,0,0,ccs,ami,nt<br>
signalling = bri_net<br><br><br>Other experimental findings:<br>When connecting one Asterisk box in NT mode to a single box (either an Asterisk box or a Patton), is does work no matter how termination is se (for this NT box).<br>
<br>When connecting one Asterisk box in NT mode to 2 boxes (an
Asterisk box and a Patton), then termination settings matter.<br><br>Anyway, thank you very much for your help.<br>
