Dears; The problem was related to something else.
The Digium card has two PRI ports, actually to get it UP, I have to configure the two ports and both of those two ports to take the timing from span 1. Why this, I do not know ! Although I am using only one E1 connected to span 1, so why I have to configure the other span !! After configuring the second span, so now one D channel for span 1 is UP and the other is down (because no E1 cable connected to the other span), now I can remove the configuration for the other span and the D channel for the first span will stay UP, but at anytime, the E1 might come back down again and I have to configure the other span port again to get the E1 up on the first span. Any advise for this? Regards Bilal -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
