<div>Hi ,</div>
<div> </div>
<div>I got your point. You have configured the Telesis Side SS7 and also configured the circuit and Timeslot correctly .</div>
<div>You have two 4E1 cards installed at your asterisk server .</div>
<div> </div>
<div>It seems to me the Signalling cable mismatching . Can you do a test ?</div>
<div> </div>
<div>1. Pull all the E1 Cables from 1st 4E1 card </div>
<div> </div>
<div>2.Put all the E1 Cables from 1st 4E1 Card to 2nd 4E1 Card and put all the Cables from 2nd 4E1 card to 1st 4E1 Card</div>
<div> </div>
<div> </div>
<div>3. Check ss7 link is up in asterisk and Telesis.</div>
<div> </div>
<div> </div>
<div>Rgds</div>
