[shoieb_arshad]

hello every body
i am a newbie to SS7 in asterisk.
i am trying to connect to connect two asterisk boxes with each other using SS7
signaling over a E1 link. i am using sangoma a101d and performed all the steps
described in http://www.voip-info.org/wiki/index.php?page=Asterisk+ss7+setup 
but i am getting error 

MTP2 timer T3 timeout (failed to receive 'N', or 'E' after sending 'O')

and also on command ss7 status it shows
all 30 channels are pending reset. 
kindly help me in this regard.
