Yes there is a problem with Signal. Signal element is always an IA5 String with length 1, not a variable length. There is a fault in h245.c.
I can send a sample capture later on. I cannot find the capture right now.
I sent a patch for solving this and some other issues a couple of weeks ago. Andreas Sikkema didn't have time to look at it at that time.
Some part of my patch is not needed anymore, due to changes done by someone else (regarding NonStandardData).
I'm out travelling right now, so I haven't been able to look more into the IA5String stuff that I tried to patch also with my patch.
