SA,
thanks for the interesting analysis. on my side, i still don’t see what is the cause of the problem. I’ve analyzed such an issue in alcatel lucent network (exactly the same problem).
We did an Abis trace as well, but with no luck.
A channel request
–> an immediate assignment with same random reference
–> an establish indication.
the problem is that the channel request is not followed by an establish indication… but how can you link these two messages ? There is no common reference on the abis… therefore I could not manage to extract the *faulty* channel request.
What do you think ? did I miss something ?
