it looks like your telco don't sent you GRA on your GRS.

I have similar problem with one of my telco - DGT does not recognize my CGB 
message because of the range=32, with other telco it works fine.

Pozdrawiam / Regards

resetacknowledge' from peer)


| Hi all,
|
| Thanks to the generous help from Mr. Pawel Ratajewski, I have managed to 
solve the initial alignment problem(was using the beta version 1.0.93 of 
chan_ss7 and it is solved by downgrading to 1.0.0 following some reboots). 
But I still couldn't get the ss7 link ready for making calls. All CIC are in 
'idle reset pending' status. The below's is the log messages.
