[asterisk-ss7] SS7 link setup between Telsis and Asterisk

[Mesbahuddin Malik]

Hi ,

I  got your point.  You have configured  the Telesis Side  SS7   and  also
configured the circuit and Timeslot correctly .
You have two 4E1 cards installed at your  asterisk server  .

It seems to me the Signalling cable mismatching . Can you  do a test  ?

1. Pull all the E1 Cables from 1st 4E1 card

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


3. Check  ss7  link is up in  asterisk and Telesis.
